My friend messed up his coil wiring now car wont have spark.... I will tell him to check wiring since i notice theres a positive short to ground somewhere.... He probably mixed up some wires going to the coil now the distributor aint getting power..... With negative battery cable disconnected i still get a 10V reading between negative terminal and the chassis..... I will look for the short now
@@jokoprasetyo2898 depends on the coil. Look up your part number and check the specs on it. 1,800 ohms could be ok for 1 coil but way out of specs for another
@@jokoprasetyo2898 generally speaking on older coils anything over 8 ohms is suspect. The high tension side could be anywhere from 3,000 to 15,000 ohms
It is only a test of the general health of the wire. If it is out of range replace it, if it is in range it is most likely still usable (unless the outer insulation is cracking missing or damaged)
I was able to do the 2nd part of the test with my multimeter set on the ohm setting at 20K and I got roughly 7.5k reading I think you said if it's over 5K the coil is good. So does that mean my coil is good?
@@Foxcanfixit On pins 2 and 3, I got no reading at all, it just remained at .1 on the ohm resistance setting. Keep in mind this is from a 1992 VW Corrado VR6 ignition coil module. Your coil is a bit older so my location points are different.
Coil packs are tested different, check the VW forums or look up an online service manual for it. There will probably be an ohms test, but the acceptable ranges will probably be different, and you could have an ECU trigger problem you could test for as well.
@@Foxcanfixit This is not a "coil pack". It's an ignition coil module just to clear things up sorry if I didn't emphasize that. So yes my readings are correct and I have confirmed from other viable resources that my ICM ignition coil module is burnt out. I've already received a new one today mission complete.
FYI I found out later that you need to place the meter leads both inside the secondary leads(Coil Sockets) to get the reading 15m to 19m for the dual Onan coil.
Thanks for the video. Did you check leads prior to the check to see if they zeroed out? I believe you're supposed to subtract that number from the indicated reading.
It’s probably OK as long as it’s steady. This was an externally resisted coil, internally resisted ones will have different specs, but low and steady for outside and high and steady for inside and it’s usually ok
