Hi unraudar,

Thank you for the donation.

When the ignition switch is turned to START, do you have battery voltage coming out of the Red/Bklack wire to the starter relay?

Does jumping terminal 2 and 8 cranks the starter?

Did you test the alternator main wire for bayttery voltage?

Was the alternator tested?
