G'day - I've just spent an hour rigging up an anderson on the plug on the GU. Got it all completed and did a check of the voltage at the plug and it was 25v...
So I went and checked at the battery and it was also 25v...
Any clues as to what the issue may be?
I have no dual battery set up to confuse the issue and I did check the multimeter and it was working fine.
