Wax Capacitor on P-15 Fuel Gauge

[Ward Duffield]

Hello Group

I am in the process of rewiring my 1946 and I see an old wax/cardboard condenser attached to the fuel gauge.

Amazing what a bright work-light reveals.

Does anyone have details on this part; its rating, part number, modern replacement, function?

Thanks for any help!

I know that on my 1939 Desoto on the fuel gugae there is a hole for a condenser and I think this was to stop radio static. But I have not found any information on the speifics on the condenser. Thought this might shead some light on the topic.

Thanks, Rich I have been working on these cars since 1972 and this is the first of these add-ons I have come across.

It slips right over the fuel gauge terminals.

FYI, the dealer- installed radio is a MoPar 602, by Colonial Radio, LIC, NY, which has been recapped already.

the very specifics are shown on the cap you picture....

0.5 mfd is a 0.5 μF = microfarad . Does it say 100V or 300V ?

Red ring shows minus.

Old capacitors dry out and may short circuit. Changing them is always preferred.

You need a 0.5 μF polarized Electrolytic Capacitor or 0.5 μF non-polarized Polyester Capacitor. 

Both will work as arc and noise suppressors.

I would choose an axial Polyester for easier soldering.

Thank you for the help! It is 100Volt.

I found some good info in the attached Radio Manual figures.

Has anyone ever seen the grounding braids installed on their firewall grommets?

I will be the first on my block, I'd wager.

If anyone wants the entire MoPar 802 manual, let me know, and I'll email a .pdf copy

Thanks

Yes grounding is useful if you listen to AM stations. Please post pics when you are done.

@Ward Duffield, I'd love to get a copy of the MoPar 802 manual (the email is fbarbieri@gmail.com).  My car doesn't have that condenser, but the original fuel gauge was changed years ago, so maybe that's when it lost it.

 

Thanks in advance!
