What You will Need
Spray vinyl electrical insulation
Silver core solder
Your boat ignition switch needs replacement when the switch does not light up fire in the engine without efforts. Wiring the regular three-post ignition switch for the outboard may be a hard task to some boaters who do not know the technical details of the boat wiring. It is indeed an easy process to wire a boats ignition switch. Usually, all ignition switches have the same basic work despite its additional features, i.e., the basic circuit is the same for all the ignition switches. These ignition switches are basically used to control the power going to the primary side of the starter solenoid and the shipboard. When the switch is in the on mode the circuit is then completed. These ignition switches are used in boats, off road cars, industrial equipment and generators.
These switches are easy to mount and durable. Even though these ignition switches are not used widely because of lack of knowledge about them, they will be in wide use in the mere future because of their long lasting nature and broad applicability. It has 6 terminals on its back, with two of them marked with the same letter, a boat’s ignition switch wiring appears to be a challenging task. But it can easily carried by following the steps given below.
First, use a hole saw tool to drill a 1-1/2 inch hole in the dash at the location where the ignition switch has to be mounted.
2: Sliding Down the Bezel
Then once the hole is drilled, slide down the ignition switch into the bezel which will be offered with the switch. Then, thread the plastic nut onto the underside of the switch and tighten it such that it holds the bezel in position.
3: Soldering “B” Terminal
Next, pull up the ignition cable through the hole in the dash. The terminal on the switch which is marked as “B” has to be found. Then find the red wire in the ignition cable with a purple stripe throughout its length. Using soldering iron, solder it to the “B” terminal along with the silver core solder.
4: Soldering “A” Terminal
After soldering the “B” terminal, it is time to solder the “A” terminal. Solder the purple wire into the “A” terminal. Next , solder the purple wire with a white stripe along its length to the “C” terminal. Then, solder the yellow wire with a red stripe on it to the “S” terminal.
After soldering the terminals mentioned in the previous steps, solder the black wire with a yellow stripe to any one of the two terminals which is marked as “M”. Then, solder the black wire with a white stripe to the another terminal which is marked as “M”. Finally, using the spray vinyl electrical insulation, spray all the terminal connections. Now, install the ignition switch in the dash with the mounting screws that are already given. You have successfully wired your boat’s ignition switch.
Tips And Warnings
- If you leave the ignition switch of your boat turned on, the starting battery will go down. Use a house battery along with the starting battery and change the battery selector switch to the house battery and turn off the ignition switch.
- The wiring information about the boat is found in the boat owners manual that specifies details about the ignition switch.
