Ok so first off Hi im new and need help. Alittle background. I bought a used 98 zx2 and i just had to upgrade my lighting to some hid projectors done RIGHT. Not just hid bulbs in a reflector housing but a full on retrofit. I found some already done and I started to use them. My car didnt really like them as it has a short somewhere and i will figure that out. But first I need to get a couple new ccfl inverters before i can start work. they are 900v 50hz 5ma-8ma inverters. What is a good quality one that Probably is low profile and takes up very little space and is waterproof.

I'm sorry you lost me? K you need inverter? Or voltage regulator? What exactly are you trying to install? Led Turn Signal?
Why 900V? Frequency 50 hz ok & low amps cool? You are talking dc right?...

What is the relation between the CCFL inverters and the LED turn signal? The title of your post may be misleading, or is it the content?
LEDs are not driven by CCFL inverters. You need an LED driver, essentially a regulated current source.

Sort this out and give us some better and clearer information, please.

Ok the content is the misleading part at this time. Right now im asking for a good recomendation for a ccfl inverter as the angel eye is ccfl.

As for the led turn signal it is direct plug and play with a 12 volt regulator. It is already load resisted to where no extra resistor is needed for the turn signals. I would like a bases of where i should begin my testing to get it sorted out and working again. It might be my car but it might also be the lights. I will upload a picture of the back of one of the led boards. You can assume that all boards look the same (dont want to tear them all off as they are silliconed in place)

You cant see it very well but in the second picture it looks like a blown resistor. Is it actually bad or almost there?

Ok so that will be my starting point. Are you able to tell what type of resistor it is?

Loosely based on the other resistors in the picture... maybe an 11Ω or 110Ω resistor...
Ideally, we need to see all 4 colors on that resistor.

bands are red red brown gold. it is a 220ohm at 5% prob a 1/4watt but not sure

But i dont quite get how he has it wired up. There is 114 leds on the board and its 12v. Im pretty sure the leds are 3 volt 50ma how many would be in a series?

There would only be 3 (4 tops) in series, and each series string should have a resistor... but they may have cut corners and put some LEDs in parallel without their own resistor... hard to tell from the photo.

not sure what its worth but i took a multi meter and checked the resistance thru a couple different resistors and it had said .217 on auto and identified as K. same goes for the resistor that looks bad.

So its looking like it might just be my car. when i get the car running again and the battery charged i will switch the side that it is on.

Sounds good. Keep us updated.
It's still hard for me to understand how that thing is wired internally with the coating they put on it...

Yea i dont understand why he put a flex coat on it like plastidip. Doesn't make much sense
