My B2150 won't start Turned key to warm up ,when I go to start position, it clicks once and all dash lites go out Cleaned up ground frame connection and battery posts and charged battery Same thing Any help appreciated Ken
You have ....
a poor connection somewhere......
you have a battery that is supplying "volts" but not enough amps....
you have a very weak battery - it can happen for no real reason, poooof it is dead!
all of these can be tested.
Easiest thing is to do swap out the battery .....if that fixes the problem, you nailed it.
If problem was not solved - then you now can look at the other problems one on one.
I'd rule out the battery first and connections/cables first. Can you swap out the battery from your IH to check? If you still have problems, start checking cables, all connections, etc. Even with a new battery, cable, and clamps on vehicle once, it turned out to be a bad ground. I did also have a similar issue once that resulted from water in the key switch.
