Ward Duffield Posted January 19, 2019 Report Share Posted January 19, 2019 (edited) 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!

desoto1939 Posted January 20, 2019 Report Share Posted January 20, 2019 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.

Ward Duffield Posted January 20, 2019 Author Report Share Posted January 20, 2019 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.

Plymouthy Adams Posted January 20, 2019 Report Share Posted January 20, 2019 the very specifics are shown on the cap you picture.... Quote Link to comment Share on other sites More sharing options...
chrysler1941 Posted January 20, 2019 Report Share Posted January 20, 2019 (edited) 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.

Ward Duffield Posted January 26, 2019 Author Report Share Posted January 26, 2019 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 Ward Quote Link to comment Share on other sites More sharing options...

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!
