Voltage gauge reading low

[Jonathan]

Cleaned the main ground on the frame in the engine cradle. It didn't look bad and it barely gets wet but I decided to check it anyway. It had a thin dark gray layer of corrosion/sediment on the frame and fitting. I cleaned it with sandpaper and got another .5-.7v on my gauge.

Going to clean my fan grounds next time she goes in the air. It's been a minute since I have cleaned any of them.

Is that the one that’s together with the engine mount on the passenger side?

It's on the passenger side but it's above the big engine ground. This one secures on the frame rail just below the expansion tank. I believe it runs either into the coil compartment or main harness(I didn't trace it). You will need a 13mm spanner for the nut on the bottom and a socket with a long extension for the top. Pretty easy to get to though.
