Hello all!
I bought an old 1980 Starcraft Questar 191b with the Mercruiser I/O 140 in it.
I'm working on getting it running and have some electrical issues.
One of my friends who is a great mechanic wanted me to try to find something online for the electrical wiring.
I was wondering if anyone had a wiring diagram handy that they might be able to share for it.
The last guy who owned the boat hacked a lot of stuff up.
I had it running then lost all power to the helm last week.
Im going to need to do some serious work on the electrical.
Thanks for any help!

Eric
