I have a 1990 Honda CRX Si. When i drive the car with the headlights on, my gauge cluster goes crazy. Both left and right signal turn on and the hi-beam light turns on. My gas gauge goes to the very top and also does the tempature gauge. Plus my rpm gauge goes dead. But as soon as I turn the headlights off, everything goes back to normal. Also my car will not start if it sits for more than 3 hours. Im always having the disconnect the battery when I go to work. Any answers???

It's just a speaker. Vehicle has no flasher relay - body control module (computer ) does that function. Suggest you put correct blubs back in .

Turn Signal Lamps
When the turn signal switch is place in either the right or left turn position, the turn/hazard request circuit is pulled low, through a resistor. The body control module (BCM) uses the resistors to determine if the left or right turn signals have been requested. The BCM then supplies an ON-OFF voltage to the turn signal lamps and turn signal indicator on the selected side of the vehicle. The turn signals receive a ground at G101, G401, or G403.

I bet you didn't get something plugged in all the way

More info needed. Is this a hatch back, sedan, or CRX? Is the odometer mechanical [old style] or digital [LCD numbers] The vehicle speed sensor [located behind the speedometer in the instrument cluster] drives both the speedometer and the odometer [mileage meter]. It sounds like an electric problem in the instrument cluster. Remove the instrument cluster and take it to your local speedometer repair shop. Look in the yellow pages for them. Or simply buy and install a used instrument cluster from a junk yard.

you'll need to take the gauge cluster out and disassemble it. then take off the pointers making sure to note where they're pointing to. then apply the new face. and wire power and ground. put the pointers back on and reassemble.

go get the battery and the alternater tested. its free at like auto zone and it covers your bases before spending lots of $.

No dipstick...you verify by havin car first on level ground then.Then when on stable ground remove the 17mm filler plug on upper passenger side of transmission.if fliud flows out of filler plug than level is fine.if does not flow out whenplug removed.RECOMMEND STRONGLY using a honda brand manual transmission fluid in this transmission..it does wonders for shifting or gearing issues.

this is not the problem of fluid, this is a major problem of transmission. The transmission must be detached from the engine, which you cant do by yourself. the transmission can be repaired but i dont know mechanics in your do it. otherwise you have to replace the transmission.

You have to check your brake switch with your brake foot Padel.

Have you adjusted the clutch cable enough to allow it to disengage the clutch ? try that first. Is this the original clutch?

I would recommend flushing the tranny fluid. you could go with GM synchromesh fluid found at the GM dealer and it will make the shifting buttery smooth. I use this all the time. appx 2 quarts.
