Testing the resistance of the coil pack connector harness side, on one side I'm getting a reading of 1, and on the other side I'm getting a reading of 0.04, the resistance is supposed to be 0.77-0.95 OHMS. What am I doing wrong, I've got the tester on 20M, on the lower settings it doesn't read anything other than 1. Last edited by Cody Dyck; October 07, 2009 11:02 pm UTC. DSM owner since 1998.

Someone please correct me if I'm wrong, but I think you should have it on the Ω 2000 setting and be looking for a number between 770 and 950.

When I switch the ohmmeter to 200k, I'm still reading 1 on the 1-3 side, but I'm reading 47 on the 2-3 side. But I'm doing my testing on the harness side of the connection, is this diagram talking about the coil side? If I have the car running and I test the voltage, all three wires are getting power, just not the same amount. DSM owner since 1998.

If the ECU side getting power through all three wires does that mean that it is good? DSM owner since 1998.

If you want to check your wiring you need to do it from the Ecm to the coil, find the pinouts for the ECM and check each wire. So you'll need a long wire to reach from the meter to the ECM. But usually meters have a 200 ohms and under setting, use this for checking wires. Then it will switch to K ohms (some meters) Meters can be confusing because they can all have differant settings. For example my cheap at home meter has 200 ohm 2000 ohm 20k ohm 200k ohm and 20M ohm setting. Depending what setting your on it may give you a reading in a decimal point or no reading at all...the confusing part. They have all these settings because of lack of room in the display and percision, just like a calculator. So basically understanding it and having it on the right setting is key. Ohms is hundreds K Ohms is thousands M Ohms is millions Hope this isn't confusing, sometimes when I use other peoples meters I even get confused.

I'm just waiting for my replacement CAS to come in and if that doesn't work I was actually thinking about calling you. Originally Posted by Jay king Yes this is for the coil side.

I found the ECU pin outs and they seem to be good, I've tested them and I'm getting power. It has to be the CAS, it's the only thing I haven't replaced. DSM owner since 1998.
