Please tell me what this is? A blue plastic drum with a black ground (earth) wires from each end. It connects to the same connectors as the Bi-metal stabiliser (in U.S. is spelled stabilizer) to the two green power input wires. Ohm meter registers no continuity. I suppose it is a fuse or type of circuit breaker. The stabilizer is suppose to reduce the 12 volt from the battery to 10 volts for the gauges on the instrument panel. The other end of the stabilizer is a Light Green/Black wire. A little help? I'm trying to restore a 1974 Jaguar XJ12. Love this site, last time ran into a guy who was wonderful helping me with the AC. I've been trying to tell him THANKS!



Is like a fuse, circuit breaker or some reducer. Does not show any continuity with Ohm. What should this read?

 

post a picture?

 

Looks like art number C45222 "Suppressor" in this illustration

Posted an image just for you Jose. 1st time doing an edit to a post, hope is good enough for you.

Thank you Doug, you are getting on the Christmas List (lol). I found the exact part like you said C45222. Having some computer issues now. Will try again later.
Thanks again, can't say that enough. Paul

 

good job with the image Paul, first time I see that part, must be exclusive to the 12 cylinder XJ.

 

It's shows in the Jaguar Series II XJ6 catalog as well. I wonder what it is supposed to suppress?

a spike arrestor?

it looks like the cylinder found in the video cable from the monitor to the computer.

 

I have one of those behind the instrument panel.

If it's a foil capacitor (compatible with the age of these cars) it will show open because there's an insulator between 2 sheets of foil, one wire connects to each sheet.

I think there's a voltage regulator somewhere behind there that works with points (DOT had one); when voltage gets just right they open to prevent frying meters, and when voltage is low enough the points close again so they're constantly vibrating. Without the spark suppressor (capacitor) the points would eventually burn and/or weld themselves together -- or so it was explained to me when I was a wee lass.

I sort of like the idea of a bi-metal stabliser, it sounds like something that would need dilithium crystals on a Star Trek episode :-)

 

Replacements today are solid state electronic without any capacitor needed.... used by others...MG and etc. Have one in my '71 XJ.
