resistor wiring in car amp conversion - 55HP 1968 Johnson
Hi all,
I have come across the following instructions ( see below) for converting to a car amp system. My question is how to wire the resistor. Sounds like I should have a resistor , condenser and wire to the points all off the negative terminal. Does this resistor the resitor is wired neg terminal one side and grounded to the block on the other?
I am confused because I inline seen resistors wired inline with the positive terminal so to cut down on current at low rpm and not burn out the coil.
I would appreciate if someone could clarify for me where the resistor goes. I have in the past run the coil without any resistor but think I may have burned it out because It no longer runs and am now replacing it.
INSTRUCTIONS:
Converting an Outboard Ignition,
From a CD cd to a Coil Type Ignition
To change from a cd (capacitance discharge) amplifier to cd coil on this motor is a simple 12.
1. Remove pre 70s and coil.
2. Use a 12 volt low resistor coil that is pre 70s one that is used with points.
3. The hot wire going to the amplifier connects to the positive side of the coil.
4. Next the wire coming from the points connects to the negative side of the coil along with a condenser.
5. A resistor should be mounted to the block and a wire run from the negative side of coil to the resistor. Should you not know what a resistor is you can most likely find one at your local junk yard it is the ceramic looking block most likely mounted to the fire wall on most cars with points.
6. Finally you will need to make you a coil wire to run from your distributor to the coil. I used the coil wire off the coil I took off the motor and cut it close to the coil because one end needs to have the screw that screws into the distributor and the other end you will need to make up to fit the coil.
Once this is done you are ready to check your spark and head to the water.
