To start, I'll say I don't have the "proper tools" the manual wants you to have to test the alternator, the best I've got is a multi-meter that reads AC, DC, and resistance. I've gone through and checked what I can on the alternator itself: the resistance. the field coil reads about 7 ohms, and...

I'm chasing an issue with my Battery/Charging System. When I start the bike it turns over aggressively and the engine starts and runs. At some point in the near future (between 20-40 miles) I will grab the clutch, the bike will die and then the engine won't turn over again leaving me stranded...

Howdy. Owner of a 75 CB750K and after several years of a flat bar decided to go back to a more upswept OEM handlebar. Upon conducting the swap, I noticed the rats nest of wires in the headlight as well as many mis-matched twisted together wires from one of the various POs. So, I purchased a main...

So after some 'starting' issues, my 1982 CB750C now has a larger electrical issue. With the battery fully charged, I found when I turned the key that the battery voltage would essentially collapse (no lights, nothing) to pretty much nothing. I eventually found that when I removed the 4 pin...

I was getting my 1982 CB750C all buttoned up after getting some light maintenance done for the riding season, and I made a stupid mistake: when plugging in my 2-prong flasher relay back into its location, I plugged in the green (ground) wire instead of the grey signal cable. Heard a click when...

Hey everyone. I have a bad spark unit. There are some OEM ones online but I sort of hate to replace an old part with an old part from someone I don’t know. Are there any good aftermarket spark unit replacements? Anything with a heat sink? Thanks for your ideas!

I'm tracking down an electrical problem in my 1978 Honda CB750a Hondamatic. The tail light fuse (7A) blows immediately when the ignition switch is turned on. I've determined that there is no short in the tail light, and it's working perfectly if it is connected to a 12V source. The tail light...

Hi, I have a 1981 cb750c DOHC which has been having ignition issues. I spoke with Murray from Murray's Carbs who recommended an accel kit if I wanted to spend a bit of money so I bought one and received the 14403 kit with 3 ohm coils. On the box however, in bold letters it states (NON-CDI)...
