Your alternator may be on it's way out. Places like Autozone will put a machine on it and check it for you for free.........you coudl check to make sure the serpentine belt is tight on the alternator pulley. There's also a possibility the bearings in the alternator are getting dry and starting to get tight and will eventually seize up and then cut your belt when it does. It could be the gauge, but I would get a free check up at your local parts store first.
The voltage gauge on the Blazer is not the most accurate (cheap) When using the signals the voltage draw on the system is enough to make the gauge move slightly.
The fuel gauge fuse on 1998 Chevy blazer is located in the front of the blazer. It is on the driver side next to the hook latch.
We replaced the temperature gauge in my 1991 Chevy blazer what is the normal operating temp?
The fuse box for the fuel gauge on 1998 Chevy blazer is located on the driver side. It is near the hook latch.
check ground first
13.9 to 14.2 volts.
because you suck it until it hurts
210 to 220 is a safe range.
Bad sending unit in the fuel tank.
About the only thing they have in common is the headlight switch. Have it checked out.
You lift the hood and look at the pressure gauge.
In the tank, it's called a fuel pump module.
The check gauge light on a 2000 Chevy blazer could be several things. The oil could be low or the other fluids may be low. Take notice of all the gauges. One or more may be out of its normal parameter notifying you there is a problem.
If the gas gauge is not reading there is possibly a short somewhere between the fuel tank and the gauge or the gauge itself is broken. I have found that in most cases the sending unit in the tank has failed.
The oil pressure gauge may be fluctuating on a 2006 GMC Sierra if the oil pump is failing or the sensor is defective. This can be the first indicator of a potentially catastrophic failure.
Find out what's wrong and replace the broken part. It's either a fuse, the sending unit (in the tank) the gauge (in the dash) or a damaged wire or connector.
Need to check the fuel pressure with a gauge. May need a fuel filter too.
Perhaps a defective voltage regulator- not regulating voltage Perhaps a defective gauge-
Connect a freon gauge and the freon can to the low side ac port. With the ac running on high and the engine running, open the freon. Let it flow until the gauge shows that the system is full.
The fuel pump may be fine but the sending unit may not be. The sending unit is probably the most common cause of fuel gauge failure.
Either the gauge or the voltage regulator device on the charging system has failed.
The voltage does not depend on the gauge of the wire, but on the thickness and type of insulation.
I believe they should run at abt. 200-210 with a 195 thermostat . It will also depend on what engine you have. 4.3 liters run on the gauge right at 200
It is located inside the fuel tank along with the fuel pump. The fuel tank must be dropped to gain access to it.
That light notifies you that one of the gauges is out of its normal parameter. Check the temp (overheating), the voltage (not charging) and the oil pressure gauge (low or no oil pressure).
