Test transistor or replace so you can rule this out.

Quoted from 1stpingalaxy:I did a quick and dirty test just now by connecting the negative to the ground strap, and then touched the positive lead to the metal tab on the large TIPs, and confirmed none of them were shorted via a continuity test. But I know thats not an end-all test and might not tell me much without testing each one individually -- which I will try to get to tonight.
Yes that is a quick test but best to test each leg of transistor as well as the pre driver tansistor which i believe is a 2n4401
I have seen several times where they will even test fair but still fail under load so even if they seem good may not be the case.
