We took the boat for a spin on the weekend to check out all my modifications (nearly every weekend over winter!) - some of which worked great (new cabin locker) and some of which didn't (masthead light plug lead 6" too short).
With a fresh batch of
fuel the outboard started up and ran very sweetly (thanks to many for their advice
), and I took a few readings on my multimeter at the end of the outboard cable at fast idle:
Orange wire 1 - 2: ~12VAC
Orange wire 2 - 3: ~4VAC
Orange wire 1 - 3: ~9VAC
I just assumed it was AC but these readings were jumping around everywhere, so I'm not really sure. I then plugged the wires into the rectifier thingy (best guess of which leads were which) and measured 19.9VDC between Red & Black without the battery connected. Is this ok??
I then stopped the motor and plugged the battery in (reading a bit low at 11.6VDC), started back up again and away we went 'cause others wanted to use the jetty and my wife was keen to get out for a sail.
I don't have an ammeter so I don't know if its charging or not, but there were no sizzling sounds or smoke coming out of the cabin..
Anyone know what else I should look for??
Thanks,
