Thank you Tom. It was the 5 amp one

OK!!!!! Got it Is was the 5amp ign. fuse. thank you all that have responded Sometimes you just have to go in another direction then come back to it. I very much appreciate the input from such talented people

I did not try the boost switch as the the engine turns over fine. Temp is in the60s-70s yes tried rear start. no change. 13.4 v Thank you Tom. The engine turns over fine and the voltage is 13+ v . I rebuilt the Big Boy. Just wondering about the indicator lights on the C Bds in the rear box. it's been awhile since I had been in that box, but isn't most of those indicator lights supposed to on when the ingnition switch is on?

I pulled into the park on the 2nd of Feb. I had not even tried to start it untill yesterday afternoon. I'm not sure if this contributed to this or not, I did not disconnect the umbilical cord for the toad. We had some pretty heavy down pours. the other day the brake indicator light for the AF one brake system was on. I disconnected the cord and the light went out. I checked the but there was no short in the cord. That was the only thing I did in the engine bay except to check all my fluids. Yesterday I opened rear electrical box after it wouldn't start and found the voltage discrepency at the Big Boy. I also noticed that I had no indicator lights on any of the boards at that time, however after I R&Red the Big Boy i now have only one indicator light on. I don't recall witch one but it is on the board that has the 30 a ignition fuse which i have checked and is good. I hope this helps jacjaw.

Did yours also indicate an "engine com failure",or it just would not start? My engine turns over but does not start and the guages swing wildly back and forth. I took the BIG BOY apart and cleaned and polished the contacts as I had an almost 2 volt differential between each terminal. not sure where to check next. I also checked the 30 A Ign fuse. I'm at a loss. I'm in Why, AZ so there isn't much here. Any help and guidance is very sincerely appreciated.

I would like to thank all of you for bringing up the the conditioning of our batteries. We as full timers do not nessasarily think about it, well, at least I did not. I will now start periodically conditioning my batteries.
