Delta-Q Charger - 913-3600 - 36V - Lightning strike

[Marc-21]

First off, hello and greetings from Germany
I came across this site while searching for information about Delta-Q chargers.
I have a Delta-Q Quiq - 913-3600 - 36V charger for a golf cart here that, unfortunately, got hit by a lightning strike.
It killed two Schottky diodes, the isolating relay, and the resistor R9 next to it.

Since the resistor was unfortunately completely destroyed and neither the resistance value nor the color codes are readable,
can anyone here help me and tell me the Ohm-Value of resistor R9 next to relay K1?

Thanks Marc

No usually lightning. R9 100 ohm is a typical failure of smps on daughter board. Worth a shot, I guess.

Thanks a lot @Inwo

And indeed good point, could be also something else.

I’ll take a closer look at the other pieces of the PSU at the weekend

Smps chip and circuitry are midle of daughter board. Almost impossible to remove. Not easy, but i have repaced the chip surgically, in place.
The start up resistor carries the load from input rectifiers, until charger boots and the real 5v supply fires up. The only protection if smps fails, iirc, is the resistor itself.
