Grid Heater randomly coming on.
 

I just installed my Smarty Jr. in Fuel Saver mode and took it for a test drive when the Grid Heater light came on with a chime from the dash along with it. The truck ran like a champ nothing other than the light with the chime. Any tie to the recent Smarty Jr. install? Please help!! where does the relay for the grid heater mount so i can check that. I set my truck back to stock to see if it happens again. More to follow.

thats weird.................when this happened did it draw power according to yer gauge?

Dont notice a draw but im going to trouble shoot tomorrow clean batteries and wires ect.
