all in one dash instrument

[tim10034]

HI.. everyone. i have a problem with my instrument panel..its a one piece like cars have ....the fuel ,voltage and oil pressure gauges stopped working...they all show no readings..my other gauges in the dash ie rpm,speed,trim and temp are working fine...any suggestions???thanks

Start by looking at the all-in-one ground (-) connection.

rabbit....where would the all in one ground connection be???? do u think that if my other gauges in that all in one work then the ground should be ok????thanks i also found out that its called an automotive style dash gauge...???

I don't know what comes in the new boats, but I assume this is analog and not a set of digital readouts.<br /><br />If analog, 18rabbit is right. To kill all your gauges there must be some common problem, and the ground is the best spot to start looking. <br /><br />Just look for a common wire/pc board trace that goes to all the gauges - the minus side if they are marked.<br /><br />If these gauges are all on a PC board like auto instrument panels, take a very close look at the board, especially where the wires attach. You might see a hairline crack somewhere. Make sure you look closely - I use a jewelers loupe. If you find one just resolder/repair.<br /><br />Can you describe what you have in a little more detail (analog/digital, mounted on a PC board vs. all wired, etc.)

jack ...its an analog mounted on a pc board....half of the gauges work and half doesnt....i looked at the wires and it looks like one ground and one positive is coming in...

I agree with Jack L, The circuit board has "traces" or connections that carry ground and +12V to all gauges. It sounds like one of the traces has a hairline crack that is causing either the ground or +12V connection to be lost.<br />Get a DVM (digital volt meter) and follow the circuit board traces and find the loss of ground or +12V. Once you find the break, scrape the trace and solder over it.

With half working and half not I suspect all the working ones are grouped together. Something like the right half works, left doesn't.<br /><br />If so, start looking between the working and not working guages. The broken trace is probably somewhere around there.<br /><br />waterone1 is rigt, a DVM is very important tool to have to fix the problem

Re: all in one dash instrument

thanks guys...i will try to look at it a bit closer....now the hard part is to get the plastic cover that is rivited around the circuit board off.....
