What I have done so far.
Battery Tested good at shop.
Cleaned all connections-
Did voltage drop test 1.514v at Ground , .543v at Positive. ( I know they're high, read on )
Voltage at battery when cranking 10.6v , voltage at starter 10.45v
I'm starting to think the starter is causing the voltage drop that i'm getting because it is so excessive. I pulled the starter apart last night and with the 4 brushes against the commutator it is pretty hard to turn by hand. I'm guessing that this is an issue. If I release the springs on the brushes it spin freely.
So is it my starter/worn brushes causing these voltage drops ?
