Thread: Battery dud or wiring somewhere?

Hi Pete, having a battery reading of 12.95 shows you may have a fully charged battery but a stuffed battery can show the same thing, and with the amp meter showing such a high charge going to a battery that should be charged, well I think you need to get the battery tested before you do anything.

Another quick test to rule the battery in or out, as being the problem. Get another battery and see if you have the same hard starting problem.

If the motor is still hard to start, then check all the cabling and terminal connections.

Good thinking

Having a think about where I can borrow a good known battery

I was trying to avoid buying another battery

Your battery charger may be stuffed. I would say you got a partial charge only, so the battery needed much more charge. 12.95V with the charger recently disconnected is low, I would expect at least 13.5V with a fully charged battery.

More importantly check the charging voltage with the engine running. It should not exceed 14.5 volts or thereabouts when cold.

Pete - I think you mean volt meter??? The isuzu has a factory volt meter not ammeter.

If it is all the way over to the right your battery was at ~14V while driving.

I would check/clean the battery terminals and connections - and if that doesn't help try another battery as drivesafe mentioned.
