 |
|
I put power to my PS Engineering PM501 intercom last night for the first time and have a problem that has me at a dead-end. When I powered it up, the fuse blow immediately. I metered the power lead to ground and got infinite resistance which tells me that there are no dead shorts in the wiring. I moved the power circuit to a breaker, just to eliminate the fuse from contention, and it also popped. Again, no short to ground with the meter. When the unit is switched off, power can be applied and the breaker will stay latched. This also appears to tells me that there are no dead shorts in the wiring. It is only when turned on that it blows. Is this a problem inside the box that I may not be able to troubleshoot, let alone fix? Any thoughts on what my options are here, maybe something I have overlooked?
Thanks,

If you purchased the unit from PS Engineering call them and they should
give you an RMA for a free repair. PSE has always gone over and above
for me both personally and through the shop. If you purchased it second
hand, call them and see what they can do, I'd bet the repair wont be
very much.
Based on your report of the failure, I think the unit has an internal
failure. It doesn't sound like it should be that complicated to repair.
It sounds like a power control problem.

Mike,
I have the same question into PSE via e-mail to their customer service address. Yeah, I was thinking the same thing. I made ultra sure that I had no shorts to ground as well as circuit protection in the loop before firing it up.
