Dead battery's

Recommended Posts

Has anyone had problems with battery drain since installing smarty sr? I put fass in at the same time as the smarty and since then if my rig sits for more than 1 day it's dead, they are 1 year old cat battery's

Good morning! the Smarty would only demand extra juice as it is loading onto the ecm. The ecm demands the 12.6 volts during a flash. No power draw after installation.

 

Thank you!

Look at how you wired in your relay to power your FASS fuel pump. If you don't have it on a ignition "on" switched power source relay will be constantly powered. Had that happen to me with a Pak brake system.
