Hi All,
I’m new to posting on the board, however over the last nine months I’ve visited the board many times I found it a fantastic source of information. During that time I’ve taken a 1973 Rover P5B from the menacing steel jaws of the car crusher to something I’m really proud of and drive on a daily basis. Unbeknownst to all of you, I’ve benefited enormously from YOUR knowledge. This is a wonderful platform where owners share their, experience and expertise to help solve the challenges attached to owning a Rover P5B, the information I found here was invaluable. My thanks to all of you for getting me to the chequered flag. A virtual bottle of champagne is on its way to all members.
Before we reach the finishing line there are two more problems I need to resolve. One an intermittent problem and one hot coil syndrome!!
The intermittent problem:
For some reason the feed side to the main fuse (No 1) breaks down and the engine cuts out. Can anybody tell me the source of that feed and does it run through a relay be reaching the feed side of the fuse?
Hot coil:
I’ve fitted a Lumenition electronic ignition with short term success, the engine fires up with little or no effort but after about an hour the coil becomes so hot it breaks down and the engine cuts out and I’m guessing does irreparable damage to the coil, I’m now on my second coil.
Having spoken to a very helpful chap at Autocar Electrical he supplied me with a new mega spark 4 coil and a ballast resistor which I duly fitted. The result is that one of my 4 dogs will not leave the house due to the car back firing obviously it has caused post-traumatic stress to the poor guy.
If I wire the coil without the ballast resistor the engine runs just fine but I’m back to the hot coil.
The coil measures 1.3 ohms.
The ballast resistor measure 1.6 ohms.
When I try starting the car with the ballast I get 12v on the feed side and 6 v on the delivery side which is just not enough to fire up the engine. When I eventually start the engine with the ballast it runs horribly.
Any suggestions would be gratefully appreciated.
Dan.
