Popping Sound when pressing glow plug switch ... no cranking

[Chevybrit]

Ok so i'd been working extensively repairing a wiring fault with the 1009 for two days with the radio on and lights on off on off whilst diagnosing the problems ... finished up went to crank it up and when i held the glow switch on it made a popping sound and the dash lights dimmed .. it began to crank but stopped.
Figured the battery was low due to all the messing around and the light bar had also been on.

Q. could the glow plug have a fault and drained the battery ??

hadnt noticed the popping sound before?

batteries reading 11.3V so its low and they seem to be connected +to + so has this been converted to just a 12v start up??

currently charging the batteries with a trickle charger .. batts still wired up on the CUCv

Thanks Guys

Has one of the alternators been removed? Did it crank before?

All good ... just jumped it off my other truck ... just think the battery was low

A lot can go wrong trying to start these with low battery's.
Search the threads and you will see.

A battery as low as yours I would have fully charged first before anything else.
It will take a long time running the engine to get it back up to full charge.
