I'm looking for a little help, fixed my '99 748 so well it won't start now. I had a problem with her stalling at what I thought was temperatures of around 210f. Ran it for a while tonight to check cooling fan and it came on around 205 plus or minus. Thinking maybe it was the RR I pulled the battery, removed neg. then pos. all with the key off and kill switch off. I unplugged both connectors for the RR. I then re-attached the battery, pos then neg, with the RR unplug so I had access to teh connector terminals and took all the reading per instructions on Electrosport troubleshooting page. Everything tested per spec using the Diode test function. Disconnected the battery, re-attached the RR cables, and put everything back together, relieved that I didn't have to invest in a new RR. Lastly, connected pos then neg and torqued everything down. You guessed it - she wouldn't start. Just turned over but never fired. I then took everything apart again to check connections but still no luck. Anyone have a clue? Did I do some serious damage to the ECU or RR by connecting to the battery during the test? Any help is much appreciated. Thanks to all.
