Re: 465M won't trigger

it won't trigger again just like before

Larry,?
My thought is there probably is something up with the power supply. ?Ive worked on a bunch of these and the can caps seem to fail or get marginal on the power supply rails. Its pretty easy to check power supply voltages. Remove top cover and there is three DC power supply posts along with the ground post just behind the 115 vac power switch. ?you can also check the 95v opposite side just in front of the aluminum barrier. ?Connect DVM to common and each tap measure DC, then switch meter to AC and check again for voltage. ?This should help you get an understanding if power supply is problem.

I haven't used it since then, and today, it won't trigger again just like before. It has been stored in my humidity/temperature controlled shop so I am not sure how this can happen so any ideas would be appreciated.

Thanks,
Larry
