| Re: HELP !!! All of the warning lights came on at the same time ! Keith,<br> My .02 worth would include a check of your OVP(over voltage protection)relay. Most circuits are tied to that.<br> I recently had everything shut down because the 10a fuse(in the relay)had vibrated loose. Tightened the contacts and the car('85 500SEC euro)is running like new again.<br> Good luck, John F. |
