Brushes look good, well over the 1/2 inch minimum, nice and clean. Armature nice nd clean too. Very little dust and dirt in there overall.

Thanks Mick, will check the circuits I haven’t yet checked/renewed. So far it looks like just the generator is bad.
Was already thinking of fitting the 17A alternator conversion to my project bike. Have decided to get one now and fit it to the 76. Then I can ride it and try to figure out the generator issues at leisure.

have you been running the auto ign switch for a long time or something new??
on some of the auto ignition switches, when you go to the start mode, it disconnects all power to the system. this makes sure that all of the battery power is available for the starter. on this type of switch, there is temporary contact made at the solenoid to the ignition coil so the engine will start but as soon as the switch goes to run mode, power is supplied via the ignition power wire.

That ignition keyswitch has been on the bike for 6 years. Don't think it cuts power to other things when momentary starter is operated by the key turn.
Power to the keyswitch comes from main breaker. From the on position it goes back to the other breakers, including the one that feeds the coil. The starter terminal on the keyswitch feeds the starter solenoid. So the coil only gets power if the 'on' terminal of the ignition switch stays live during starting.
Are you thinking this type of keyswitch is an issue?

been working 6 years, so no issue.
just wasn't sure this was a new add on. the ole chrysler products used to use a ballast resistor ignition system, in starter mode, 12v was supplied to the coil but in the run position, the ignition circuit went through the resistor to drop voltage to the coil for a longer life.

Didn't find any other issues except the generator max output being low. That'll stay in pieces for now until I get around to trying to figure out the issue. Alternator kit arrived yesterday. Got that fitted then spent ages trying to figure out where to mount the new regulator. Was planning to make up a bracket but then realised it would fit nicely between the motor mount bolts and also lined up with the holes in the mount plate. Drilled out the holes in the regulator slightly to fit larger bolts and on it went. Not the best look but will do for now as it means I don't have to make a bracket up, ideal as I'm spending a lot of time with drill, grinder, hacksaw and files at the moment fabbing up the back brake master cylinder stuff for the project bike.



Still need to fit a fuse into the wire that runs from regulator to battery, and fit the little digital voltmeter I ordered when it arrives. But it starts and runs again, and seems to be charging - up to 14.3v when running at reasonable rpm.
Need to set points and timing, and adjust pushrods, then I can try it out at the weekend and see how things go when riding it. Seems good for now though

It's growing on me, think it will probably end up staying there.
