Re: IML: electroluminescent lighting power supply

[David Dimitriou <macedonxx@xxxxxxxxx>]

Thanks Rob. 
I'm pretty sure the power supply is dead. I'm gonna pull it this weekend. I've also got another power supply from a parts car. It's dead as well. I have a parts car that I got which had been sitting in a field for about 25 years. Lots of great parts but the rats had chewed most of the wiring including the corner of the power supply transfomer. I think the rest of the parts of the power supply are good though. Hopefully I'll be able to make one operative power supply from the parts of the two. I had heard that vermin would eat the wiring  in old abandoned cars or homes. Never really believed it until I saw it first hand. Strange!

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

Subject: IML: electroluminescent lighting power supply

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
