Hi,

I am tracing a small drain. It's 250-300ma between the negative battery cable and the negative battery post with the key off, everything is off.

most of the amperage (about 210ma) is going through the glow plug relay.

The current is about evenly divided between the pins labeled "La" and "31".

"31" leads to the ground "M1" behind the instrument clusters.

La of course goes to the lamp.

With the key off, out and everything off am I correct that 0ma current should go to "La" and "31"?

This means that replacing my glow plug relay will stop that portion of the drain, right?

Please hold your fire unless you know for sure.

thanks.
