Default Porter cable 7538 soft start triac?

I have traced the electric curcit with a ohm meter and it all lead to the triac, can anyone tell me hoe to test it as I don't think it can be tested with the ohm meter?

Thanks Geno

Hi Geno

May I ask why you want to test it ??

Without a tech manual you will be just spining your wheels..

Hi Geno: The Ohm meter will tell you if a path to the Triac exists, but not if it is working. With out a manual it is kind of a best guess situation. I think that it would prove to be more productive to check the output side of the Triac on the AC voltage scale of the meter. I think that it adjusts the voltage on start up, to ramp up to the operating voltage. It would seem that you should see the voltage step up when the meter is on it and you start the router up. That's my thought on it, hope it helps.

I wanted to test it because the motor would not run. I have tested it and the triac was good but the voltage ramping device was bad and have ordered a new soft start that includes the triac and this device.

Thanks Gene
