Hey, do you think you’d ever get your hands on an old Yamaha DT1 or RT1 that needs some work? There aren’t many in depth videos of working on those bikes and they are super cool!
That key hiding thing was very popular back then. You should be checking all of those old bikes headlight housings. Really fun when you discover such a treasure like that, the glee on your face 🫵🏻😁
Dude you have a Scotland flag on your hat, all the best from Glasgow, Scotland XD
If you put some LED headlight, tail and stop light bulbs in you will reduce the load on those skinny wires, expensive but cheaper than hours rewiring
Very informative video, man! Great work! 👍
High resistance blows fuses? I = E/R. Low resistance blows fuses. A dead short is a low resistance current flow. Low resistance cause high Amperage. It’s the law man. 😂😂.
Key in a sock, can you say Easy Rider!
So lucky finding that spare key, hope the sock wasn't too cheesy though, 🤮🤣.
I don't think your reaction to the found key was adequate. Easter egg, Christmas and 4th of July!
Great video. Can't believe you found that key in the headlight bucket!
Thanks for the new video man. Im already very competent with wiring and electricity, but I still love watching videos like this just to see what other people use and where they get their parts. There’s always something new you can learn. I learn something new everyday! Ready to see you ride this machine
I was hoping that was going to be some cash – you know for emergencies. BUT that was awesome – what a hiding place for a spare key!
I have been lacking in my commenting. Another great video! Can't wait to see the entire series for this bike!
Ha! Wasn't expecting the key find That was great
Great video matey.
Your no nonsense delivery . Gives folk the confidence to have a go themselves.
Well done sir 👏👏👏
Excellent video on repairing/rejuvenating the wiring in an older bike! Also loved the extra ignition key stash in the headlight bucket, classic 4 sure. That electrical terminal stash is a great thing to have, sure makes life easier with rewiring.
I remember rewiring the entire charging circuit using GM style weatherpak connectors on my '79 CBX turbo bike because Honda used a 14 gauge wire for battery charging and it always melted the red connectors in the harness and the reg/rectifier plug on quite a few CBX's(and other bikes) I've seen. I also ran 12 gauge wire all the way through the harness(untaping/taping that sucker was fun!)up to the ignition switch plug, solved a lot of voltage drop issues with the bike.
Problem solved, still works perfectly some 20 years later and charges a perfect 13.6 to 14.1 volts. Thanks BJ!
Finally the Key reveal episode! I don’t really see how hiding a key would help if you needed tools to access, but maybe the motorcycle goddess was looking out for you when the previous owner had the idea to tuck a sock in the headlight bucket. So random and brilliant.
What a way to start a Friday off work when the kids get a snow / cold temperature day. 9°F
Love all your Videos BJ! They are so helpful! I am at similar point on my 73. Both #1 and 4 plug caps were open circuits so gotta replace those. I use 4 in to 1 as well. I'm replacing both coils because the plug wires are rock hard but will keep them because they ohm out correctly. I just want to thank you for the hard work you put into these instructional videos! I used your previous one step by step to rebuild the carbs on the 73.
Should of gotten rid of those shit bars with the wiring
another great video, keep them coming!
Kudos to fixing the harness, those boxes with sorted new connectors is my dream solution. I must admit I probably would've just gone with a m.unit or something similar, but keeping it and just fixing the bad parts is probably a lot easier 👍
KEY!!!! fantastic.
Man I've gotta buy me some of them electrical tools.
Now I know where to hide the spare key. For real!!!!
I'm not sure about the plug caps you have, but some on Kawasakis I've worked on can easily be disassembled and cleaned up inside. The resistor is a little fuse-looking thing, with a spring between the spark plug connector and plug wire terminal at the other end. Often, these internal connections just get corroded, so you can take them apart, clean them up well (Caig Deoxit is great), reassemble, and you're good to go.
I was definitely expecting drugs hidden in that mitten
Funny thing is I've been rewiring a tractor at work the last 2 days, completely building an entire harness from scratch with relays, fuse blocks, ignition, everything takes time, that key find was awesome, I shouted no f'n way when I saw that.
Haha awesome vid, thoroughly enjoy the electrical vids.
Great video on electrical and 750 content Thanks , can’t believe you found the key in a sock in the bucket, that’s cool
I hate electrical gremlins. Enjoyed the video B. J. Look forward to the double start-up video. RIDE SAFE OUT THERE!
What wizardry is this. I’ve never known that those plugs (7:30 or so) can come apart. Thanks . I learned today.
Nice
Did you check the 2&3 caps for what they're supposed to be? Sometimes the middle 2 are 10k ohm
That's actually s normally closed switch on the clutch. With nothing actuating it, the circuit is closed.
Hi BJ I love the close up on the difficult wiring work good camera man great video
Maybe just swap in an led h4 replacement? It won’t put nearly as much load on that wiring.
Was that a 60W bulb in there? I think you can get incandescent H4s down to 35 watts, sold for mopeds. Only marginally better than a candle though. I have a 45W one in my cb750 that seems OK for brightness.
Another great video.
Mate, I cannot find your other channel anywhere. Maybe you could add a link in this channel's description/about section.
Cheers
Heyyo. I don´t know if anyone said this already but you can refubish the plug caps. You can unscrew the resistance in them and replace them. Atleast that worked on mine. Good video.
This bikes name is officially Mittens.
Had a couple of bikes over the years that i had to fully re-wire from scratch. 1 bike had a harness which was actually 3 different pieces of harness with the wires just twisted together and wrapped with electrical tape to complete. That was soon put in the bin. Any new harnesses that I made for bikes didn't always follow the manufacturers component positioning, so, I used to draw up an accurate colour coded diagram to give to the new owner when I sold a bike on. I like your diagnostic techniques and your collection of connectors, bullets, sleeving etc. You have my favourite flag on your hat. 👍👍
Neat that someone else decided to make the rear turn signals into running and brake lights! I have done similar conversations to every bike I’ve ever owned! Very simple. To make them glow as running lights you just need to connect the positive lead to 12v through a 3A diode and resistor in series. This will reduce the voltage but still make then glow. When the full 12v for the turn signal comes on, the light will come to full brightness. I have forgotten the details of the circuit but some diodes to isolate each bulb so both don’t blink. There’s some more logic needed to make them work as brake lights, transistors or an “exclusive OR” logic gate can be used. I can research my design if you want to replicate the circuit. I still have a have a hand built circuit board at home, but it’s potted so I cannot reverse engineer it for you. But I have done it before!
Dude, thanks so much for soothing my OCD with neatness and organization, lol. Those electrical connectors in the sorted boxes actually made me say "ahhhhh" out loud hahaha. LOVE the wiring episodes. 🙂
man I thought a k in cash or some forgotten prerolled joints, but a ignition key. wicked….
No wayyyyyyy!! Can't believe you found that key!!!!! Great hiding spot!!
Credit to the previous owner. He cared for the bike and did a great job with the wiring. There’s no dodgy bare twisted wires and insulation tape there.
I'm looking to replace the harness/loom on a '98 Bandit 1200; (apparently it has an alternator not a stator and the electrics have left me stranded twice…)- if you have any similar projects I would be interested to see 🙂
