resistor for 12v with original 1935 inline

[CP]

Hello all once again,

just realized there is an original resistor under the dash that I never knew was there.

From other posts....i found this "14.2V / 3.5 Ohms = 4 Amps"

I'm running 12volts 1948 flathead with a Mallory electronic distributor.

Mallory paperwork requires ballast resistor. I'm running a 12 volt coil. and I have a ceramic resistor between the battery and the "+" of the coil. Plus the resistor I did not know was there. Lately, when the engine gets "hot"....it is difficult to start.

wondering 2-questions...

1. what is the "stock" resistor in ohms (original 6v system) 1935
2. from what ive read, 4 amps is what we want for any engine (6v or 12v).


I know the resistance changes with "heat"...so I'm thinking the ceramic coil I have is "too much" yet i do not know how to test hot or cold.

any thoughts? I am not knowledgeable in this...

I'm thinking I want to keep the original resistor as is...say it is 1.5 ohms...I will then purchase a 2.0 ohm ceramic resistor and be "all set" no?

I saw another post that napa has many ceramic resistors available and i think 1.8 ohms was the most i could get..

If that is the case...is it better to have more resistance or less? I'm confused.
