Normally, you only have two types to choose from. Either "Point's" or "Electronic" They both work well under normal use, but when put to the test each has it's benefits and drawbacks. Point type systems allow you much more control over your firing system such as an extra horse or two by swapping a 35,000Volt Coil in for a 60,000 or higher Voltage Coil. This then creates a much hotter spark which helps burn fuel better. Points are also easily and cheaply replaced. There main drawback is that if the points get burnt, dirty, or especially if they get "Wet", then they are useless. They must be cleaned or replaced before engine will crank, usually.
On the other hand, the more modern Electronic type is not nearly as picky about being clean and dry. That is why they are the most widely used type in the woods. There is no Hi-Voltage coil to speak of. GM's H.E.I. is more or less a self-contained unit. (remember: the less parts it takes the lesser the chances of it tearing up) They are very dependable and really even don't mind water too much. (TIP: If you've been in deep water and your truck is spitting and sputtering, trying to die, or won't even crank, just pop the cap off the Distributor and wipe it out with a clean rag and spray a shot or two of "WD-40" inside it! Stick it back on and take off!)
Their biggest drawback is price. They do last a very long time but when the "Control Box" for them goes out, you'll fuss about the price of a new one. Sometimes easier and cheaper to just get a whole different distributor from a junkyard. The $25.00 you save at the junkyard can be put toward that set of 44's you can't stop thinking about!
"SILICONE", a modern miracle for 4x4's. Get a couple of cans of clear spray silicone and go over EVERY INCH of your Ignition system with it. It will harden and form a waterproof seal that works great, even last through several Hi-Pressure Wash Jobs.
Generally, the stock wiring harness is OK for most situations. Some improvements can be made such as an add on Fuse Box(always needing a new Hot wire) or adding split tubing(even garden hose works) to those certain wires that are always getting rubbed badly. Good short prevention. |
