i was wondering if the gauges on a 92 mustang 5.0 lx are accurate? the tach reads 4000 just idleing and the temp gauge may seem a little off. anyone else with these problems? and would the fix be going to aftermarket gauges?
Aftermarket mechanical gauges are historically more acurate then electric sensors I.e. coolant temp oil pressure...ive not had a problem with the stock tach..??..i would check wires first,then go aftermarket!!..
ok thanks, i was actually looking over old service records because i just bought the car about 3 weeks ago and it says the tach is innaccurate, so ill be replacing that. the green wire on the aftermarket tach goes to the distribuator right?
Not sure if all are the same,but yes usually the green goes to the distributor or coil...black is the ground and other wires are for gauge light and to power for the needle..
There is a voltage limiter/instrument voltage regulator on the back of the gauge cluster that allows for some calibration adjustment if your gauges are not reading correctly.
However it sounds like your tach is toast.
ya like i said, it sits at 4 just idleing and will hit about 6 all the way to the floor lol. so if i went all aftermarket should i go with a new gauge cluster or individual gauges and just put them were i can
Depends on how much money you want to spend.
A whole cluster is going to be expensive.
You can get the speedo and tach in 3 3/8" and the others in 2 1/16" to fit the factory cluster though if you want to do them one at a time.
