So regardless of the fact that I think the ICU / Switchgear is fried (and my new points too), I'm going to give hooking it up a shot. Even if it is a general failure, I would be pleased to have figured out how the stock wiring should be configured. It would be a better baseline too.
So I have made some attempts to follow this nice diagram I found on the pagoda forum, and to add my notes, plus take a video of what I think I have figured out, and what I am clueless on. I am not sure, but I think I'm down to figuring out where two sets of black wires should be connected. I wonder if I'm going to have to do some continuity tests to figure this out, or if anyone here might be able to assist.
I am also concerned about my assumption that the wire that previously went to the coil positive / 15 terminal should connect to the other side of the resistor that connects to the positive. That brown on that wire seems all wrong for that. And notice that the wiring diagram from the pagoda group shows that ballast connecting to terminal 16 on the ICU which is black. So maybe I need to figure out where five wires go, not just four.
The previous configuration (when I purchased the vehicle, and it did run) seemed to only use two wires:
1) green part of green coax from points connected to coil negative.
2) the brown "fifth" wire that is in question above.
Using some logic, it seems like the brown wire in question must be a source of "hot"and therefore must be one of the wires that connect to the 0.4 ohms (top) resistor in the diagram, that I've labeled "Y" (from starter) and "Z" (from ignition).
I am a little confused as to how my setup could work to start the car unless the "run" position on the ignition switch also gets power when it is in the "start" position. Hopefully that's a small detail and. There hasn't been more cobbling that I'm not aware of.
Edit: I need to go back out there to check and make sure I accounted for all wires. After writing this down, I think I have accounted for them all. I know I labeled the five disconnected wires:
- A, B, C (all zipped together possibly making contact. Two of these must be what were originally/supposed-to-be the positive and negative for the coil. I assume the third was the coax shield for the green wire.)
- D, E (on a zip tie together but definitely not in contact)
I later discovered the wires that are disconnected where the switchgear/ICU belongs:
- two still unknown wires that come from the same "loom"/insulator coming from the coil/electrical-fuse area. Let's call these "F" and "G".
- a brown ground wire coming from what looks like diagram terminal "3" on the ICU/switchgear. (Solved)
- the green and yellow wire that appears to mate up with the green wire from the coil (solved).
So I am down to figuring out:
where do F and G connect? I assume one of each connects to the two junctions on the ICU/switchgear where (a) the green+yellow wire connect to the green distributor in net wire and (b) the brown ground from ICU 3 connects to the black outer sheathing for the green dizzy wire. But how to I tell which is which?
. I guess maybe one might possibly have some voltage when the car is on, and the other won't??? Maybe I need the correct diagram for the m130 w114.
where do E and F connect, and how do I tell which is which?
Maybe I need the correct diagram for the m130 w114.
P.S. I only paid $500 for the car, and hate to spend nearly $150 on the hot spark solution if it might not even solve my problems. That's why I've got to at least give it a shot on returning the wiring to stock. This car is destined to be a parts car some day, never a collector.
Crap. Maybe more is mixed up than I thought. This web page says that the resistor with the blue anodized holder is the 0.4 ohms, and I was assuming it was the 0.6 ohms. I guess it is possible that I can't trust any wire was left in the right place on this car, even if it was serving no purpose. Dang. http://mb.bolinko.org/15/warsztat-ma...-ignition.html
