I'm installing a rebuilt Mercarb with electric choke on my 2006 5.0. My previous carb had a fuel enrichment solenoid and not wired for a choke. I'm going to the boat this weekend and hopefully get the carb in. I've been reading the service manual and looking at online videos, but still not confident.
The service manual shows a purple/yellow wire coming off of a starter solenoid terminal as the power source for the electric choke. Has anyone used the starter as a power source before? Is there a closer source of switchable 12V power?
There is a single spade connection on the choke for the positive lead. It looks like I use a screw on the choke face as the grounding point.
I'd appreciate your inputs and questions on this project.
Mike, Donald, jparsons; this is plan B for my carburetor rebuild project that you were helping me with last month. Throttle shaft was frozen so I gave it to my mechanic. He couldn't fix it and gave me a rebuilt carb to test.
Mercruiser typically uses a generic harness that supports many applications. There already may be the connector laying there to connect to the choke. If not power should come from the oil pressure switch one the engine is started. This is the same switch that powers the electric fuel pump. The starter soleniod only provides power when cranking.
