Re: IML: electroluminescent lighting power supply

[randalpark@xxxxxxx]

One light can suddenly short out and that is exactly what would happen. 
Poof! the system would go dark. I wouldn't write off the power supply 
until checking for shorts in the system. The power supply isn't usually 
the problem. It can be and so can the headlight switch, but usually not.

One thing to note is that the power supply is mounted in a spot where a 
leaky windshield gasket can ruin it. If the power supply is rusty 
looking I'd check for leaks before replacing it.

Hi Dave,

Well, ofcourse you can check for shorts but if you have a short then 
the whole EL system would be dark and it won't have worked for a few 
months.

However, you can easily check the entire system for shorts by pulling 
the white wire that is going to an Electroluminescent item one by one.
If the system then suddenly lights up you have found the wrong part of 
the system.

On the otherhand, the power supply maybe at fault. But first make sure 
it is properly grounded and that it is receiving 12 V battery power.
Unplug it from the wiring that is going to the dash, give it 12V and 
check for an AC output of approx. 250V.

If not, it is time for rebuilding it. This shouldn't be too difficult 
as long as the transformer is allright. You will find all the info you 
need on the IML site (repair section).

Good luck,

Robert

I found the write up on the web site. I was actually able to repair my 
push button electroluminescent panel and the wiper dial using the 
technique detailed in the write up. Worked great! However recently my 
power supply just up and died. Everything worked great for a few months 
and then poof. So now it looks like I'll need to repair the pwr supply.

My question is could I have done something wrong during my repairs that 
would have caused the power supply to die? I'd hate to get my power 
supply repaired only to kill it again because my system had problems. 
What should I check for to ensure this does not happen again? I figure 
testing for shorts would be a good idea. Any other suggestions?

Thanks,
Dave
