Resistor installation I want to start my 36 but want to temporarily put a resistor in between the coil and the ignition. Does the resistor have to be grounded or can I temporarily use plastic ties to hold it in place. Thanks, Blast.

BEWARE: Resistors get VERY HOT. Be careful about it's proximity to anything that may burn. Plastic ties will melt. Use solid core wire to possibly hold it in place. AGAIN....Resistors get VERY HOT!!! DD . |
Re: Resistor installation Thank you for your response.
I appreciate it. First time for a drive in this club cabriolet And didn’t want to burn out the points. Thanks for your help. |
Re: Resistor installation Pictures, we love pictures, although I can't post them myself.

Re: Resistor installation on my 39 i mounted resistor right on coil using the coil nut to hold it.

Remember ....like I said....resisters get HOT! I mean frikken' HOT! And the last thing you want to do is cause a COIL to get HOTTER in any way, not to mention that VERY HOT resisters can possibly melt that plastic-like case on a coil. I believe I'd be looking for someplace else to mount that resistor, but what do I know? DD . |
Re: Resistor installation Dick,
You shrinking violet; what do you know? In a word, lots! |
Re: Resistor installation Most ballast type resistors have either a ceramic outer protective cover or some form of metal shield like the original 1936 type. I don't know if the OPs system is original or not.
The original type was 0.8-ohms if I remember correctly and it was matched to the OEM Mallory design coils used in those years. Use one of this type if all is original and make sure it is insulated from any grounds. The originals were mounted to a small circuit board that included a fuse mount. If the distributor has been converted to use the can type coil then no resistor would be required if the coil is set up for 6-volts (1.5-ohm). If it's set up for 12-volts the it would need a 3-ohm primary coil for 12-volt or it would need a 1.3 to 1.5-ohm external ballast for a 1.5-ohm coil. |

It does not need to be grounded. [QUOTE]]It will be wired in SERIES in the wire from battery to coil. Would that be true for a 1941 V8 Truck? Are there two Ballast Resistors? It appears that way in the schematic |

It does not need to be grounded. Quote:
"Chill" [sic], as there is ONLY one resistor. I've looked at that drawing, and I can see how you might assume that possibly being TWO units, but this picture below should clear-up any confusion as to how they were built back in those days. To make things easy, run a wire from the ignition switch to FIRST nut on the resistor. Connect a second wire at SECOND nut and run to coil.

Re: Resistor installation The "first nut" on the resistor is on the left. Correct?
Is the fuse holder related to the resistor? I'm working on a 1941 firetruck for a volunteer fire department. Thank you. |
Re: Resistor installation Who sells the correct resistor?

The fuse holder has strictly to do with LIGHTING circuits. DD . |
Re: Resistor installation What is the effect of not using a resistor?
What does a resistor do? I heard that without a resistor the coil will overheat. |

Re: Resistor installation From a Google search
A resistor controls the flow of the electrical current within a circuit. Resistors are made from materials like copper or carbon, which make it difficult for the electrical charges to flow through a circuit. The most common type of resistor is a carbon resistor, which is a general purpose resistor, best suited for lower-powered circuits. Some other common resistor types include the film resistor and the wire-wound resistor. Resistors are essential to many electoral circuits, and they can be applied to a myriad of different applications. |
Re: Resistor installation Thank you fellas for your info.
I appreciate everyone’s input. It helps me understand the need for the resistor And the correct inline wiring. Thanks again, Blast. |
