Default Strange electircal problem? Need help!

Hey guys,

I have a 2004 GS430 with 114K pampered miles, has always run great, no problems. It is lowered with BC coilovers. Recently, I had a new AC unit installed. Since then, several times at highway speed when I hit a heavy bump the whole electical system seems to turn off for about 1-2 seconds (AC turns off,, service lights come on, radio turns off, etc) then come back on with no problem.

Can anybody give me an idea where to look?

Well, even though I had checked the battery, I rechecked it based on your feedback, and indeed, the negative terminal was a little loose. Seems to be fixed -- thanks guys!!!

I finally figured out the problem. My positive battery cable was slightly bent upwards and was making contact with the hood causing a s/t electircal short, not to mention burning the underside of the hood. Easy fix!
