Help! I've got a 3ym20 in our yacht. When I engage the ignition key it won't crank. I can hear a click from the starter motor but that's all.
Suspecting dead batteries I borrowed a good one off a neighbouring boat and tried to jump it. Same thing. Then I checked the batteries with multimeter and they both show 12.5 volts so look fine. Check voltage on the starter motor terminals also and that also shows 12.5 volts.
I'm stumped. Can anyone help?
Thks, Phil
