i do have a voltmeter.. i followed the procedure on th Snap-on Modis scanner..
You have a 94 correct? It doesn't have an obd2 connector for a Modis.
my a9 circuit is blk/blu. my a23 circuit is grn/wht.both circuits have voltage on them w/ a light and voltmeter, and are located one on top of the other on the connector. not the same as the pic.. assuming i have the correct terminals the switch doesnt click... the pic show one + and the other -
My tester beeps for continuity, not sure what the ohm reading is supposed to be. Does yours have a beeper?
nope... no beeper
not sure but during all this testing, connector "A" the blk/blu wire got pushed in @ the connector and wasn't making its connection.. it was making connection w/ a light and the voltmeter. when you plugged it back up.. no connection... well repaird that.. so far so good.. no mil light no codes and no surging problems... going to test drive..
works great thatll be bout 40 bucks preciate it...lol
