Hi Tony,

Thanks. Yes, I'd seen the riocar.org stuff, that's where I read about the Negative Spike Bug (which incidentally sounds *exactly* like a problem I have).

The battery is brand new, (it's condition has been checked also). The battery icon problem happened before the new battery / new alternator, and has happened since then although it did go away and then come back. It went away right before I upgraded the charging system, but we upgraded anyway. It stayed gone, but came back a few weeks ago (the upgrades were made last year).

Strangely enough, the first time I drove the car after starting this thread, there was no interference whatsoever! Typical, eh? But still, this (and the battery icon) have been problems that come and go. Fine for a few weeks, then back worse than ever. This is what makes me think it's some kind of loose wire behind the empeg. These problems are the worst!

Can anyone give me a firm answer on whether or not I should ground the empeg sled to the chassis? And if so, how?

Thanks
