I know ya did. I was making a funny.
So the brushes aren't absolutely terrible, but I'll probably be replacing them soon. I've actually yet to measure them..Lost my tape measure..hah
But I'm assuming they should be replaced once they reach the indention mark? The left brush has a corroded spring, so I'll be replacing both anyway. The right brush is almost too short, so yeah.
"The mechanical regulator models ('70-'79) work opposite of the solid state bikes. The regulator feeds power to the rotor on the positive brush (the insulated one) and it grounds all the time on the negative brush. So, to perform the regulator bypass on a pre-'80 model just apply 12+VDC to the positive brush with a jumper from the battery and watch for a rise in charging voltage at the battery terminals when you rev it up just like on the solid state equipped bikes."
I'm trying to follow Curly's guide, but I'm honestly not quite sure how I would do this..Do I just hook up a positive jumper cable to the battery and to the positive brush?
I'm terrible with wires and electrical things..
I don't want to do anything stupid, so yeahh. Just going to wait and inspect other parts of the system before I try anything.
Edit: just found my tape measure! The left brush is 10mm long and the right brush is at 8mm. Geezz. How long is a fresh one? So replacing these is a must for sure.
