I think my signal wire for ignition module and ignition coil grounded out

Good morning,

Do you mean the wire on the negative side of the coil?

Did you verify power on the positive side?

Roy

Using test light for the module I have feed and ground with key on, but when key on the white wire the signal i have no light. clip on +battery pointing to white wire light is on, turn the key and light goes off for both module and coil connection. is that normal?

Put the clip on the ground on the battery. Test for power on both sides of the coil. then crank the engine. The test light should flash on the negative side of the coil while cranking.

Crank and test for power feed and test the other wire that comes from the module? White and black wire? I ignore the white wire the tachometer.

Yes. Test the white black wire to see if the module is working.

I tested the feed on both both coil and module light stay on.. checked ground light stayed on . Checked the white/black wire to them n light stood on.. and the clip was hook to (-) battery. they all got little almost nothing dim because of the amp of the starter.

If the light does not flash, the module is the issue and needs to be replaced.

Roy

I replaced it four times already

Within 2 weeks

What brand and were are buying them?

Duralast from AutoZone :(

Ask them to upgrade you to an AC/Delco. Make sure you use the dielectric grease on the muntings.

Then retest the system.
