Re: [TCML] microbrute DRSSTC

Alton: Sounds like you went over the coil with a fine tooth comb. Check the 
 output devices. You might call someone in the tech department at Eastern 
Voltage  Research and ask if there are any quirks in the circuit during 
start-up or  anything else that comes to mind. Good luck.

Hi
Yes I have a break point yes I mess with  the primary too. Still no out put
at all, the 5 amp fuse side does not pull  any current at all, it should 
pull at 
lease 3 1/2  amps.
Thanks

the  turns on the primary if you haven't done so.  There are a few on 
Youtube  you could look at, including my own.
