speedmeter, mpg meter, and radio problem

[mr.vang]

after i change the brake fluid and fix my gas meter the speedmeter, mpgmeter and radio doesn't work anymore. it was working before. i checked to all fuse, still good. during the brake fluid replacement and removal of the gauge (to fix the gas meter) i unhook the -+ battery couple times, rip out the brake lining wire from the pads. there couldn't be anything that would cause the speedo, mpg and radio to die. the mpg is jumping from 0 to 40. it is suppose to be around 30-15 when driving. any clue guys?

is it the speedometer or the tachometer? if it's the tach (rev counter) then it's a fuse. i cant remember which one off of the top of my head, but one of the fuses will take all 3 of those things with it when it goes.

fuse 12 take speedmeter and radio/stereo..i already check the fuse and its fine.

i just found out my odometer is not moving either. can broken gear from the odometer cause the speedometer to stop working also?

Did you figure out what was wrong with your tach?

nope. odometer, speedometer, mpg meter and stereo is still dead. i need some help figuring how fast i'm driving. if i'm at 2000rpm in 5 gear how fast am i driving?

60-ish

this same exact thing happened to me. Try fuse 21 if u haven't already.

[Heysüß]

yeah i would say fuse 21 but his tach is fine.

60-ish

no way.with 4.10 diff at 3000rpm it was at 65-70. i was thinking maybe 40 but not sure.

[mr.vang]

all fuse are good.

By "gas meter", do you mean the fuel gauge? Sounds like you had the gauge cluster out? I'd start by pulling it again and making sure it's all plugged in properly.
Also, did you put a meter across fuse 21, or just eyeball it?

[mr.vang]

yeah the fuel gauge. i have pull the cluster out more then 6 times. everything is plug in tight. no, i didn't touch any fuse until those were out.

[mr.vang]

update: i found out the aftermarket alarm is connect to fuse 21. Also, today i was driving and out of no where everything was working again, but its dead again. the good news is that my gauge is not broken and the bad news is that, there is an electrical problem.

bump?
