battery leads are slightly looese as im using short jump leads and a bigger battery clamped conections etc not loose in connection or touching, suitable battery, ive got the negative probe for the dmm to the neg of the battery, poitive to bare metal on frame (earth point), when the key is off its reading 0000 when the key is on i get a current reading, is that indicating a short somewhere maybe? or am i reading and doing things wrong?
