Guys / Gals,
My Sept BJ70 will not turn over to start. It is a Canadian spec truck. The problem started with very little warning. When I started it the other morning, the starter relay buzzed. I returned the key to the off position and tried it again. This time it started fine. However, there was a recurring clicking coming from the dash (could not pin down the location) while it was running. The next time I tried to start it, it would only buzz at the starter relay. I cleaned all the battery contacts and reconnected them, plus checked voltage at each battery (they were fine) but it still only buzzed. Since the truck was not home, I was able to pull start it to drive it home. After pull starting it, the clicking noise in the dash returned and continued for the entire trip home.
I have reviewed the factory body & chassis manual without luck at identify the problem source. The wiring diagram shows starter relay and an EDIC relay, but I have not been able to find the EDIC relay (the manual does not show the location for this relay). Also, I have a second BJ70 (Oct '86 production date) so I tried swapping the starter relay but even with the swapped relay I had the same buzzing from the relay.
Clearly, I am at a loss in diagnosing this and would appreciate any help/advice you can share.
Thanks
Larry
