Question Surge Guard 34750 internal noises

I have this portable 50amp surgeguard by TRC Technology Research Corp. When I last used this I heard sparking type noise coming from the internal part of this unit. the Arcing sound went away and the unit functioned. I have now tried to use it and it no longer engages. The line 1 and line 2 lights go on but the time delay light does not go on so there is no power connection after the 2min 16 sec time delay sequence. Anyone have any experiance with this. There is NO external reset button either. Thanks..

Sounds like it fried. It has to contact/decontact to work. Probably fired an internal relay that drove the contactor. SurgeGuard may be interested in the failure (I think) and may replace it if they get to have the old one to check out. Worth a try.
If not, there may be a way to disassemble & repair it, also worth the price of your time if no support from S.G.

I have that same unit and it has given great service. It might have prevented your whole coach from being fried also.
