I killed my whole bus!

Help! I moved the chassis batteries from one bay to another, and in doing so I made a spark by accident with the lead from my solar trickle charger. As a result I get the error code "no eng" with the key on, and "icu 140" when it cranks but doesn't start.

2005 Thomas FS 65, Cat C7.

Any input is appreciated.

Joe

Can't help you unfortunately, but this is a prime example of how delicate the electronics actually are on those 04-up busses.

My buddy bypassed the radiator temp sensor on his 06 Chrysler mini van, and somehow roached the ECU in a micro second. A costly, $400 mistake.

Hopefully this is not where you are now. Best of luck to you in troubleshooting and repairing your bus...

I don't really understand what you did in enough detail to have a guess as to what you might have fried, and even if I did I still probably wouldn't know enough about your bus to give solid advice. But if I were you, my first step would probably be to just check every fuse that might in any way be related to the engine, starting system, or ecu.

Start checking fuses. Take a picture before you start for reference. Needle nose pliers help a lot.

With blade-style automotive fuses, it's a lot faster & easier to use a multi-meter with a continuity / diode test function. No removal required, just touch the probes to the two exposed contacts on the back of the fuse and listen for the beep.

Of course the pliers are a great help if/when you need to replace one. If the OP's lucky, he will.

Yes, true. And also you won’t misplace a fuse like um, someone on this forum

You may, however, test the wrong fuse and spend a couple wasted hours chasing a non-existent problem based on the result like... someone else on this forum
