I replaced my grid heater realays the other day i have had a battery drain issue.. When i went to hook the fusible link from the relays to the battery the wire would spark off the battery.. Next guess is to replace grid heater.. Or is there another problem????

 

Relays control the power supply. The grid heaters just use the power. I would recheck wiring. Check for continuity accros the supply and feed of the relay with it off. If theres continuity you know its a faulty relay.

I'm betting on the relay, I had a battery drain issue and when my shutoff selonoid relay burned out my battery drain issue was cured.

 

Guess i got some bad ones straight out of the box

 

Very common these days.
