Will not change resistance

Che for blown fuse or loose connections.

I just saw a video where a fellow purchased 8 aftermarket glow plugs and also couldn,t start his vehicle. He brought vehicle to a very good diagnostician and found, that 5 out of 8 glow plugs were bad. Check resistance of glow plugs and with fully charged battery try again. Good Luck Friend.

1. Access the interval governor located above the warning chime
under the driver side of the dash and disconnect it.

2. Install a jumper wire between the Dark Green (DG) wire and the Yellow/Red (Y/R) wire.

3. Install a 2nd jumper wire between the Dark Blue/Orange (DB/O) wire and a Black (BK) wire. Either BK wire of the module should work, both are dedicated chassis grounds for the module.

4. Turn the ignition switch to the Run position and verify that the wipers are running on low speed.

5. Disconnect the jumper wires.

6. Connect an ohmmeter between the Dark Blue/White (DB/W) wire and the Brown/White (BR/W) wire.
With the wiper switch in the OFF position, resistance should indicate about 47,500 ohms.

7. Move the wiper switch to the low speed position, resistance should change to indicate about 4000 ohms.

8. Move the switch to the high speed position, resistance should change to indicate less than 100 ohms.

9. If the wiper motor runs and the switch resistance checks as stated, replace the interval governor.

1 may be alternator amp is low and load is high
2 alternator main +B to battery wire resistance to high

follow the steps, and fix it. God bless you

Be aware that the resistance is often the part that requires repair. Resistance is managed magnetically, so often if the machine is working, but the resistance isn't setting correctly or at all, check the bolts that secure the magnets. If they are loose, the resistance will slip. If the bolts are fine, check the magnets themselves by using a refrigerator magnet and see if it is attracted or repelled by the your fridge magnet. If not, the magnets have de-magnetized and need to be replaced.

1) tight the bolts tension for magnet and clean very well. and proof..if the fail
2) go to test the magnet, use again the magnet from your refrigerator magnet, for attraction and repulsion. If do not pass the TEST replace the magnet in any Hardware such home depot, etc.
God bless you

The battery was low to begin with, or the electronic timing module has developed a flaw. I recommend going back to the same jewelers and have them change the battery again, if it works they can not charge you.

Press and Hold the button next to the Light Button that looks like a key for about 3 seconds.

measure resistence between companion outputs. they should be marked on the coill pack.12 ohm nominal. mesasure the resistence of the input terminal. 3 ohm nominal. i recently had a coil pack go bad on a '97 crown vic where the number 8/2 tower was reading good resistence when i kept the meter probe steady. if i moved it around while still making contact, it would change. i was getting a cyl. 8 misfire and found a bad wire and the plug was worn funny, so i changed the plugs and wires. this did not fix the underlying problem. the bad coil pack. the vehicle was misfiring at cruise but upon acceleration no misfire was apparent. what are the symptoms the truck is displaying
