View Full Version : Hfs-3 gauge randomly shuts on and off

So recently i've noticed at times my Meth gauge will turn itself off and turn itself back on a few seconds later. I also noticed my wideband will error out when this happens but not my boost gauge. I'm wondering if i'm pulling too much current from the same source, or it's a ground problem. My Mac valve,wideband, and boost gauge are all wired into the same source (fused 10A pig tail off of the fuse box)

Any suggestions? Thanks.:confused:

Wild voltage fluctuation is the main cause of the Gauge tuning off. Rewire the +12V to a more stable source.

The tuning off is due to the start-up timer see a positive voltage ramp on the supply. The HFS3 only draws around 250mA on standby. If the trigger happens during the non-injection period, it would be caused by another device drawing excessive current from the supply.

An older fuse may have the same effect, try putting in a new fuse.
