I'm sorry to hear that. If it's a pre-2014 model, and you have the time and resources to fix it yourself, then you can use this guide:

I'm sorry to hear that. If it's a pre-2014 model, and you have the time and resources to fix it yourself, then you can use this guide:Plugged in my elcon 1.5, which is in my golf cart conversion from may 2015, and there was a few red blinks and a pop, then nothing.
Ah! I have this change, among many others, marked in red on my "master" paper schematic; it somehow didn't make it to the digital file and the post. Fixed now.i found a slight error on the control board schematic related to the 15VDC_Aux supply...
I can only guess, but my feeling is that there is a good chance the MOSFET would have survived. All it can do it put 15 V from gate to source. If the opto-isolation was breached, then could easily blow the MOSFET, but I'd expect other carnage on the U12 (NOR gate) side if that was the case. I find U12 does blow up moderately often, but you'd probably have noticed if that wasn't working.@Mike
do you think the FETS would be blown by an internal short of the IR fet driver chip? pins 1,2,3 were shorted on both U15 and U16, while 6,7,8 where shorted on U15?
Certainly. But I think without more carnage, just shorting 1,2,3 and not these to 5,6,7 should not create such a transient.Pdove said:A large transient on the gate of a MOSFET will certainly blow the device.
U12 is definitely blown internally, pins 1,2,4,6 thru 13 all shorted to ground and to the A and B out of U14 solder pads....I'd expect other carnage on the U12 (NOR gate) side if that was the case. I find U12 does blow up moderately often, but you'd probably have noticed if that wasn't working.
