whats up with that?

 

Details?
Chexk your wiring

 

the wiring behind the dash is ok like wires to lights

 

It has to be wiring or fuses.

Did you check your fuses?

Well, I guess there's a relay to check, too.

I'm no electrician, htough, I can only give you basic advice

 

all the lights? some of the lights? maybe its the bulb(s). need more details.....bra

 

Well, he says the Tach isn't working either, so

 

yea all the lights work, just not the dash lights and the tach did work and now it doesnt...

 

Fuses

 

they are ok...what cause the tach to not work is there a cable or some ****?

 

tach is not cable. speedo is. tach is run off the coil

 

so i have a bad coil?

 

hmmm....just a hunch, check the bulbs. could have caused a short and blown every bulb. Also check the dimmer it's on the left hand side close to the choke pull and the power mirror switch.

 

The tacho is run off the '-' on the trailing coil.

 

It could run correctly and still have a bad connection. Thats what mine did. On my trailing ignitor, the prongs were a little bit loose and making it to where the tach didnt work. I would clean and then give the female connectors a "little squueze" to get them tighter. Worked for me at least. Lights, I had the same problem and realized my dimmer switch was unplugged from the back somehow. I hope this helps somehow.

do al your externall ights work. Headlights, parking lights, brake light. I had a problem similar to this but a few differences. Let em know if your light work so I can type out what my problem was and how I tracked it down.

 

As for the lights, the dimmer may be shot; with a bad ground. Mine was. My dimmer is now bypassed to be brightest all the time.

 

I'm another victim of the bad dimmer. You can jumper the connection to the dimmer temporarily which will put full brightness of all interior dash and console lights to see if it works. (or do it permanently like ChasRX)
