Boost gauge no longer working after dead battery

import10188 · 12-11-2017, 04:08 PM

AS the title states, just bought the car about a week ago and finally got it shipped to me home, came to me with a dead battery as a light was left on inside. Called dealership i bought it from and it was working when they put it on the truck. Is this something as easy as un plug it and plug it back in or more to it?

Might need a little more to go on, are you sure it's a boost gauge? Nissan doesn't make a forced induction 370Z so it's aftermarket or not a boost gauge. Any other symptoms or maybe some pics of this gauge?

As per ElwoodBlues, you haven't given us much to go on. If the battery was changed, the power wire to the gauge may not have been reconnected.

It's a autometer boost gauge, I hooked a tender too the battery to charge it over night.. it's charged and runs good, just the stock gauges work, just the am boost gauge is getting no power and needle isn't moving for vaccumm.

Maybe the old owner had the car forced induced before but took it off before selling so there is no use for the boost gauge? Are you even sure it has a supercharger/turbocharger?

There should be a fuse in the power circuit - check to see if it's blown. Add-on fuses are commonly sited at the battery; sometimes at one of the fuse blocks.

I figured it out, 2 wires were cut hidden, took a bit to find them, thanks for all the help!
