the umnitza angel eyes shorted (dunno y it didn't just blow the fuse in the angel eyes) and corroded the jump start block and melted it...i'm losing 1.5 volts just across that block...multiply that by 115 amps and the block gets really hot (ever touched a 60 watt light bulb? now try touching a 170 watt light bulb...ouch).

the new block comes in tomorrow and i have to replace the wire from the starter to the jump start block as well since is started to melt...

jump start block is pictured here:

i followed the wires from the alternator all the way back to the battery to check the resistance at each point as well as the voltage at each point. i was about to bust out the oscilloscope to make sure the alternator was acting correctly but got lucky and found this.

Optima batteries are the worst!!! Once they loose their charge they never fully recharge! Stay away from them like the plague! Stick with OEM man!

Another stunning endorsement of Uminitza quality control.. not.. there was a thread a few years ago about the guy who had his car burn up from a set of angel eyes.. from you know who..

That IS hot.. amazed that the fuse didn't blow. Where was the short?

Glad to hear it got sorted out. Too bad about installing a new alternator.

How'd you catch this? Assuming it wasn't melted into a mess below... Was there anything quirky about your angel eye installation? Suspicious?

I too have the Umnitza angels and would prefer to not have a similar problem. My battery drains quite a bit when the car sits for a while... but I do have an 8 yr. old stock battery.

the problem with the AE design is that there is really only one fuse and thats only for the main 12V line. dedending where you get your triggers (on/off and fade in/out) those sources may or may not have any fuses. but the real problem are in the lines going to the AE themselves. these lines dont have any fuses at all. so in any event these wires get shorted, corroded.. your gonna short. it may not be a complete short, but enough to drain.

to avoid this, just run inline fuses to each AE

fuse check
1. main 12v
2. relay trigger on/off
3. relay trigger fade on/off
4. AE right
5. AE left

so.. thats a total of 5 fuses you should be using but most the orig design only uses 1

i'm throwing the angel eyes away, gonna get the aurora's from tom @ eas.

i'm not too worried about having to replace the alternator as i feel it is a maintenance item on this car, mine was 9 years old and had 77k miles on it.

i caught it by looking up the wiring diagram for our car and testing the voltage at every single point, starting at the alternator and going all the way back to the battery.

my angel eye install was perfect and i know it was as i did it. i even soldered the connections at the ballast to help with the possibility of a fire like a few people had.

trust me, with all the problems people have had with angel eyes, throw urs away and get the new led ones. the only reason i knew something was wrong was from the smell of plastic burning coming from under my hood

replaced the jump starting block and now the battery was charging at 13.7 volts with the car on and at idle, before i started the car the battery had gotten pretty low too (11.8 volts)

i have the car on the oem charger overnight now, i bet it'll charge at 13.9-14v after the battery is up at a higher voltage

Didn't realize you have the old Umnitza AE. I have the Orion and I don't have any problems with it.
