  • Hope you guys don't mind a longer video this week. I found a few issues with the bike and wanted to show an in-depth overview of how I diagnosed and fixed them.

    It took 2 month to fix every wiring issue of my 550 cb ss....it was my first attempt on doing something like that.
    I'm still proud of me even after watching that you did the same thing in less then one afternoon 😂😂😂
    Cheers from Italy! ⚡️⚡️⚡️

    It's much easier to replace mechanical things.

    Great work! I've had my power probe for about two years. Every time I take it out, I'm rocked for how great that tool is. I also ordered the electrical auto diagnostic shop book from the same designer. absolutely great for diagnostic work. Both auto electrical theory and trouble shooting in one. Get it. Thanks again.

    been working on wireing on my bike for the past two weeks. all the stuff you just went through... 1982 goldwing aspencade modified beautiful... your video helped me find the problem. the fix last 6 times was the fuse to the headlights. shitx 10 amp fuse blown; maybe shorted it fixing 5 other electrical projects on it. not i got her under control for her... LOL.imho,edwinstarr22

    @T25AM76 4 ปีที่แล้ว +1

    I like how you try to simplify the testing of the circuits. Before going to the easy part of testing the bulbs. Not that I understood it any better. I'm sure it's a very "drone " process for you. It's one of those things the more you do it. The more you understand it.

      What are you saying how did he know the dude's running through it on his own bike to show you how you can do it on yours not because he had some assumption that many people out there have bikes that are older than 2003 2004 and most of which all could use new wiring harnesses yet they just don't f****** produce those damn harnesses for us anymore which is an absolute f****** s*** show but that's the only way they can keep us getting new bikes is by not making parts for the old ones anymore sad I had to learn that on a 01 LS650 Savage cuz I've got a motor issue and can't get the m************ belt off because it's belt driven of course don't want to drop the f****** rear tire can't take the nut off the belts pulling the mother f***** is just straight up seized on there can't heat it from this side the pulley is some kind of hardened plastic that would melt so basically I have to drop the tire or cut the f****** belt but either way the beginning of what I said it still remains true he was doing this because he knows most people out there have older bikes and this is normally a common issue with older bikes is some kind of electrical systems not working due to the wiring

    I’m actually wiring up my first CB550 so this was excellent timing. I’ve seen most of your videos but I’m wondering if you have any recommendations on step by step wiring guides. I’m going to rewatch all of your content related to wiring but I’m not confident I’ll be able to do it yet. I purchased an m unit because of you but I’m worried I won’t understand how to wire the bike properly. The wiring harness was basically torn out of the bike when I got it so I’m starting from scratch. Any help is appreciated! Keep up the good work Man! I wish the best for you

    • @ClassicOctane

    Hey bro, need some tips on possible wiring problem. I have no tester so, yeah.
    My bike has power but neither push starting nor kick starting has any responses like a totally turned off bike. I tried jump starting through the starter relay and it started but it needs constant revving to hold its power, if you let go of the throttle the engine dies. I heard some electric cliking noise under the gas tank. So, any thoughts about this? Thank you!

      I'm leaving the front of the box open and drilling vent holes in the rear so allow airflow. Hopefully, that will be enough. If not we can look into other mounting options.

      I've got a Yamaha that had a intermittent start problem..take off your throttle handle assemble..look closely at the internals to start switch..theres a tab that is supposed to touch the handle bar to complete the start circuit..bend that tab up just a bit so it makes positive contact to handle bar..also look where this assemble mounts to handle bar..sand off the paint from the handle bar ..assemble ...should start right up ..
      Good luck...

  • @gixxer6
    @gixxer6 6 ปีที่แล้ว +1

    Great series. Quick question... you need a special charger for lithium ion batteries, yet the bike is able to charge it with no modification to the charging system... why is that?

    • @ClassicOctane
      @ClassicOctane  6 ปีที่แล้ว

      I updated to a modern REG/REC designed to work with lithium batteries. 4into1.com/regulator-rectifier-honda-cb350f-cb400f-cb500-cb550-cb750/

    • @gixxer6
      @gixxer6 6 ปีที่แล้ว

      OK, thanks. Guess that's why I often see people with newer bikes swap in a lithium ion battery without any further explanation, cos newer bikes already have a rectifier capable of charging it.

  • @manuelf.lozanodiaz3495
    @manuelf.lozanodiaz3495 6 ปีที่แล้ว

    Quick question ? I was testing my 82 CB 650 once I got the battery but I had mistakenly connected wrong did got spark at first. But the second time I connected I saw some little smoke out of the components box, and now there is no electricity at all. Where should I start troubleshooting from ?

    • @ClassicOctane
      @ClassicOctane  6 ปีที่แล้ว

      I would hook up the battery correctly then just look for power and see where it stops. Most likely you just blew a fuse or caused a short somewhere.

  • @scotttaggart
    @scotttaggart 4 หลายเดือนก่อน

    @6:22 you "throw" power (apply +12V) to the white wire. Very dangerous if you start putting 12V on to a ground wire which the headlight connector clearly has. You should have a big caution when using that feature of this tool. I don't have this tool so I am not sure what it does when you connect its +12V to ground - perhaps it has a protection circuit built in and displays a nice warning or tone. Regardless, still a bad idea to creating short circuits.

  • @oliverpaglia3305
    @oliverpaglia3305 3 ปีที่แล้ว
