hi,
Ive tried 2 water pumps on my caravan, they were both borrowed from fellow caravaners although they only worked sparodically, please could anyone supply any tips to check if its the supply from my caravan? ive bought a multimeter but not sure how to use it, any advice would really help
thanks

Select DC voltage above 12volts, you will see 2 copper coloured pads where pump fits into, place 1 probe on 1 plate the other probe on the other get someone to operate one of the taps and see if there is a reading. You can always put meter across battery terminals to see what it reads.
