I just made a solid motor mount for my EK and I tack welded it in like 4 spots. I disconnected the Battery before I welded it. I then took the mount off and welded the rest on the bench. I installed the mount and went to take the car for a ride and now my Hids do not work. Could tig welding it have shorted out the Ballast or bulb? I checked the fuses they are fine and I have power to the ballast. I thought by disconnecting the battery I would not have any problems. Any help would be great. I am so fu*kin pissed right now.

 

Did you check if there is any voltages coming out of the ballastor? If not then I am pretty sure its fried.

 

Yeah nothing its dead. I just don't understand why it would get fried if the battery was not connected

 

Because the battery is always supposed to stay connected, and the ECU/other sensative devices are supposed to be unplugged. The battery acts like a sink catching all the "drops" or spikes going into the system, and levels everything out. The other option is getting a device that clamps on with jumpercable type things, and helps out so you don't have to disconnect all the stuff. With that, the battery is still left on.

Live and learn I guess. Just be glad it wasn't the ECU or something

HID's are probably more expensive to replace in a honda than the ecu :-/

 

Depends on what part, and if the company sells replacement parts. Most Hella ballasts only cost about 75-100 bucks to replace.

i have never heard of leaving the battery plugged up... im not saying your wrong just wondering if you have something to back up this claim? personally i unplug anything that may be effected by welding on a car...

 

hids may have to be grounded better. i get that problem a lot on some cars. make sure the ballast is stting well on metal and the grounds are good enough. that may be a problem

 

Ballasts were bolted to the car. They are wired directly into the stock wiring harness. They are TL HID's

 

well, for example here is one of the products I was talking about

I forgot the name Snap-on calls thiers, so I can't find it at the moment.

Think about it this way. Just because you unplug the battery, you are still throwing around current through the same steel and wires your devices are hooked up to. Taking out the battery only takes off one power source, and you are still leaving the welder (2nd power source) at your car. The only TRUE safe way of doing it is unpluggin all the important boxes from the car to remove them from the circuit. Just taking out the battery doesn't magically protect things in the car.

 

How well do those tools work? Do you have one?

 

Have never needed one before. I jsut leave the battery hooked up and go at it, never had a single problem.

 

what kind of ballast is it?

 

Acura TL

What he's saying is, with the battery disconnected, the wiring in the car is acting like an antenna, and will pick up really strong signals, like that from an electric welder just a few feet away. That signal will travel down all the wires and cause mischief. You can disconnect the battery if you want, but then connect the red cable removed from the battery to ground, which will short out any troublesome signals.
