I have an electronic ignition and this article mentions not needing a relay. Can someone dumb down this mod for an electronic ignition?

I found this on another forum and seemed to clear things up quite well over there.

Yes..... cure your wiring harness woes instead of putting a band aid on them with this mod

www.deoxit.com is their website, it can be purchased at Radio Shack Stores in the U.S. and other electronic supply places.

+1if youve got low voltage to the coils due to bad/dirty connections chances are pretty good you have the same problem with other electrical items on bike,thats why i suggest cleaning all the connections and grounds throughout the system you possibly can to avoid further issues arising.
simple enough? :laugh:
BTW, bikes and cars run a lot of current because the system voltage is only 12V. If you have resistance build up at connectors or switches, it can do more than starve the voltage to systems: it can melt wires and start fires. This is because the resistance at a corroded connection dissipates a lot of power and it will cook the attached wires. You might see melted wires around fuse boxes on old bikes because of this type of heating.

it took 20 plus years for it to get in that shape,should be good for many more without need of major repair if done right

Thanks for the help guys. Their does not appear to be any major drawback worthy of mention with regard to the modification, except that its a modification...haha. Shortening the current path and reducing voltage drop seemed like enough of a reason to look further. From what these posts say, it sounds like the electrical systems need to be monitored closely and maintained regularly for proper function and to minimize malfunction. That being said, I still dont see how the modification has a downside..........I still see value in the mod even with a clean system, for preventative reasons of course.
My primary objection to the mod is couched in the million relays I have seen fail in my illustrious career in electronics (they are one of the most unreliable electro-mechanical components). Many of them fail with the contacts fused together (won't open) in which case it would leave you with a 12V hot wire attached to the coil with no way to turn it off (unless you start unhooking wires). Main power lines that don't go through the ignition switch make me nervous.....
And if you do decide to put in the mod, make sure you get a very good relay with gold contacts or it will give you grief. BTW: relay contacts also have resistance, you need one rated for at least 20A.
