Dennis in CT Posted October 8, 2018 Share Posted October 8, 2018 So I have a very well maintained 84 Rolls Silver Spirt that is a Sunday every once in a while driver. Took it out for a drive the other day - parked it - came back an hour later and turned key - no power. Nothing. Not even the annoying buzzer. Fortunately it was parked next to my shop - tested battery - totally fine. Cleaned terminals, still nothing. Have the factory service manuals, but they are rather useless really and I need to know what I should be looking for between the battery (in the trunk) and ignition. I literally have NO power. Not even a dome light. Checked fuses, relays, even pulled the dash apart and pulled out the ignition switch, which appears fine. Any Rolls folks out or anyone else have a thought of where to look next? My only English car. Thanks Link to comment Share on other sites More sharing options...
hchris Posted October 8, 2018 Share Posted October 8, 2018 Simple check, hook another battery up see if it makes a difference. Link to comment Share on other sites More sharing options...
Grimy Posted October 8, 2018 Share Posted October 8, 2018 Check the wiring diagram for a circuit breaker with a reset button. Over 30 years ago, a lady friend's 1975 Olds Cutlass (yes, I know, not nearly the same car) had the same ailment after a stay in a parking garage, and she had it towed to my place. The circuit breaker was just above the driver's side kick panel on that car. When I reset the breaker, the courtesy lights came on and I knew we had it fixed. Near the battery I found an old cheap pair of pliers, so I suspected that someone tried to highgrade the battery (remove the good battery and replace with a junker) while the car was unattended, but the miscreant had accidentally touched the positive and negative, then abandoned the attempt. Even for a RR, there may well be a similar circuit breaker, but from your description I have no clue as to how it may have been tripped--your next project if it is not the battery or a connection thereof.

Grimy Posted October 8, 2018 Share Posted October 8, 2018 And another possibility is a fusible link incorporated into the wiring near the battery. Link to comment Share on other sites More sharing options...

Dennis in CT Posted November 14, 2018 Author Share Posted November 14, 2018 Turns out there was corrosion on the terminal where the battery cut off switch is in the trunk. Problem solved. Thanks 1 Link to comment Share on other sites More sharing options...
