Anyone successfully bench test a tripminder. I just want to power it up to see if it works in terms of lighting up, and button functions.
Tried today. Put 12v to pin 3 and ground to pin 9 (connected to pin 7 by jumper wire). Nope.
Tried again like above with 12v also on pin 5. Nope.
Tried again like above with a ground added to pin 7. Nope.
Tried another known good tripminder. Nope.
Nope = nothing happens.
Ideas?
Here's the pin out from the sticky for quick reference.
Pin 3 is Ignition power (hot in run)
Pin 4 is the dimmer from fuse panel & instr. illumination
Pin 5 is KeepAlive power from fuse panel ( bat.+)
Pin 6 is Fuel Flow data stream from pin 34 of EEC Module
Pin 7 & 9 are grounds
Pin 8 is the speed input from the VSS to pins 3 & 6 of the Speed control ECA.
Check out the differences in the early 86 (left with butt connector installed) wiring versus 88 (right). Dash was untouched in this early 86 so the butt connector was likely factory unless someone took the dash out to route the harness behind it.
