Re: zilla "check Engine" light question

Hello David,

This same thing happens to me once until I did a modification to my battery
feed circuit to the controller. According to Otmar, he said turn the
ignition key to the on position, pulse a bit when you get the Ignition Led
on and then turn to the Start position to get the second Led indication and
than release back to ignition.

I had the habit of turning the ignition key right to the start position
which I may only get one indication light on which stays on. Turning the
ignition key off and re cycle will clear this up.

In my setup, I have two addition battery contactors plus the main contactor
which are turn on my the same control 12 volt relay. What happen here, is
the main contactor would come on a micro second sooner than the ssfety
contactors and the main contactor does not see any input voltage, causing a
momentary error. I then install another 12 volt control relay off the
ignition position, so the safety contactors would come on first before the
main contactor does.

Sometimes a momentary high resistance connection between the battery will
cause this indicator to lite up.

Normally when this happens to me, it will work normally on the next start
up.
