Npr 250 Isuzu batteries are losing voltage (24volt system).

Customer Question
Npr 250 Isuzu batteries...

Npr 250 Isuzu batteries are losing voltage (24volt system). Batteries are ok. Could this be due to earth leakage and if so how do I find out, thanks. *****: Have you tested the battery with a voltmeter? And can you see if it's leaking or not?

Checked this morning. Batteries were fully charged yesterday now down to 23.5 volts. No visible leakage.

Mechanic's Assistant: What is the model/year of your Isuzu?

1999 npr 250

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

Its a motor home. I changed the accommodation to a 12 volt system and had to remove a reducer from the original setup. The cab is still 24 volt, this is when the 24 volt system started to lose voltage

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

How to I track down a possible earth leakage? Thanks for the help.
