Remove pos cable from battery for about 10 second


Do you mean the NEG.? Always the negative cable...

Tom Harmon

As an engineer I have always regarded disconnecting the Positive or "Supply" being preferable over the Negative based on the effect induction has on a collapsing field ... In reality .. it make little/no difference in a car so ... whatever floats your boat


Thank you for that, I was taught that you disconnect the neg. So the collapsing field will run to ground verses generating a voltage spike?

Tom Harmon

In many complex systems it's preferable to remove the supply due to current flow through diodes and capacitors. If you recall the early days of engines with "points" the negative (ground) was broken through the points to induce voltage through the coil ... so engineers favored breaking the negative for induction.


Thank You...
