I have done several ERR installs now with most things going well. This will be my first MTH conversion as I have a Premier Greenbrier that lost it's chuff and whistle long ago. I need help on the connections though. Please see the photo:
The four multi color connections are for the tether. The black seems to be the ground as I traced it down to a lug on the rear tender truck (no pick-up roller). But, maybe not. Can anyone tell me which are the two motor taps, and which two are the ac hot and ac ground? The tether wires are matching color so this will tell me what wires to use where on the ERR hook up.
In addition, I was told that the rear tender light is in jeopardy if I just hook it to the ERR board. If so, would I not just add a resistor between the board and the LED? If so, can anyone suggest what resistor and what side of the LED to put that on? Why would the rear light be in trouble but not the headlight... again IF this is true.
Thanks to all!
