My initial checks showed ~110 millivolts at the brake light line with the brakes off.
Soooo.... to be sure I put a relay in-line to insure that it was zero ( at the cc only )
with the brakes off. Not happy with that, but it was mainly for test.
BUT.... I did not hook the NC relay pin to ground. I have ABS and from what I
can tell the millivolts come from the ABS ECU line on the brake light circuit, and I
ain't messin' with the ABS! I THINK the mv's come from the ABS ECM checking
for working brake lights. Pull the bulbs and you get the full ~12V.
Maybe new bulbs would pull it all the way down..... or maybe not.
I've got an interesting PM I have to go read again about the tach sig input.
I drew up a circuit for the signal last night using 2 transistors, 3 resistors,
and a relay to isolate the circuit when turned off. Will it work? Should....
Thanks for the info on the speed sensor. I was digging through my old TTL
chips last night, could probably divide, but not worth all that.
I'm impressed with the feedback. I figured everybody would laugh and think
'just buy a new one, dummy!' I looked at the Mccruise, but ~$1000? Dayum.
I'd buy a throttle lock before I'd spend that!
Of course, I still keep thinking that it's got to be something simple that I'm
overlooking. The mention of many failures make me feel a little better, but
that's the first I've heard of that.
