Hello,
This is my first post to this forum. Please forgive my ignorance as I'm not a mechanic. I'll try to provide the best information I can and follow forum etiquette.
Pics for everything I could find about the engine model are posted.
Problem:
I have a Volvo Penta 5.0GL that has no power to the positive terminal on the coil.
Question:
I've read everything I can find on this forum that's related to my issue but when someone asks, "Does the coil have 12v on the positive terminal when the key is on" they always say yes. So I'm not sure what to do when the answer is no.
Read on if you're into the long winded stuff
Background
After finally resolving some fuel delivery issues (happy to provide details) she was running great. Of course anything that's going to happen will happen on the water so after taking a lap around the lake she abruptly died as if someone had just turned off the engine (this has happened before). It happened again about half a dozen times on the way back to the ramp. She restarted quickly every time and ran for a while but when she died she died very abruptly. It didn't seem to matter how far open the throttle was.
The next day she fired right up and idled well for about 10-15 minutes. I stopped and restarted her several times without any issues. I suspected it was water in the gas so I shut her down with plans to drain the tank and refill her with ethanol free gas. And that was the last time she started for me.
I drained the tank and was surprised to find nothing but clean fuel.
Having tested the fuel system from the tank to pump and filter (both replaced) to the carb (recently rebuilt) I went back to basics and tested for spark. I honestly thought I was just going to eliminate spark as a problem but found no spark at the cylinders. So I checked the coil and I get little to nothing on the positive terminal when the key is turned to the on position.
I have some related questions about what appears to be a 50amp fuse labeled 'ignition protection' where the 10 pin connector (pics uploaded). There is a red wire running from the positive terminal of the coil to the 10 pin connector and I'm wondering if this is something I should be looking at?
