do its job.
Oh there's nothing wrong with the FW on the E15, that's the E20's problem. I'll work on that issue later.
Didn't realize the late model E15's used the reverse the armature trick of the E20's. Swapping the field is a fine idea, but if you go into reverse while moving you will instantly blow up the relay. Wish there was a way to put a big snubber on those points.
