Think I am getting there, just want some confirmation, i bought a new battery and it is reading 12.5 volts, when i connect it, it drops to 4.5 volts, so dissconect both terminals and connect a multimeter to the negative wire, and find the earth on the inicators but i touch the other side of the indicators i get the same reading, so i am assuming that i do have an earth problem, if so ,just got to try and find it
Thanks for all the info.
