This is a dumb question but I’m a very curious person and I need to understand. What is the point of the switch if the diode will do the same thing? Redundancy?
Trying to diag a buddies bayliner 205. After the engine warms up, the 15amp fuse blows and the engine shuts off and can’t be restarted unless you put another fuse in. I’m trying to figure out if the diode in the tks is bad or if we have a wire that’s grounding out somewhere. I can’t find any...
