Hfs-3 gauge randomly shuts on and off

[dsm1gb]

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.

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.
