class A 330 diesel wont shut off,

I posted this about a week ago and a man from 706 area code called and we went over some possible solutions. I lost your number but here goes. Engine shut off fixed, repair shop wired new alternator wrong and had wire that allows small current from batteries to back feed fuel pump. You also had ABS light as did I. Problem was at circuit where test for fault codes are. Button to read codes was locked into test position and would not come back out, replaced board and light is now off.

I'm the 706er. Glad they got it fixed and thanks for posting the solutions. I posted my solution too, replacing bad diode solved by shutting off problem.
