I have a 99 SN GT-40 EFI. The other day we came in from skiing, turned off the key (we leave it in the ignition), turned off the ignition breaker and left the boat. Later that day some folks stopped by and noticed that my Check Engine light was on. The key was still in the off position and the ignition breaker was off (out). Finally, to get the light to turn off, I turned the key, engine cranked and light went off. I thought it was strange but but then it got stranger. The next day I went down to the boat (we hadn't used it again as the water turned rough the next day) and the Check Engine light was on again - since the sun wasn't on the boat I noticed that the depth finder/water temp gauge was lit up as well. Same thing to get the light to turn off. Any ideas as to why this could/would be happening with the ignition breaker off? Thanks

I guess nobody wants to jump in here I'd take my trusty multimeter and do some checking to figure out where the power is coming from. As a start, check the output from the breaker when it's open/off and also the Ign terminal on the keyswitch when it's off too. You'd expect zero, but you never know till you check it  I think you have a 2 plug connector for the light, it seems like you'll find some voltage there and you'll see what color the wires are and be able to trace things backwards. Here's a link to a 2001 model year dash pod wiring diagram, it's for a keypad system but the rest of the dash and instrument wiring should be pretty much the same Warning light is at the top center of the diagram. http://www.planetnautique.com/CorrectCraftManuals/2001/2001DashWiring.pdf" rel="nofollow - link |

| Thanks Keno - I retrieved my multimeter from home - nothing is ever where you need it - and I've been waiting for it to happen again to start tracing. Once it happens, I'll post an update.... |
