Points Replacement Chips Info

[tommyhnavix]

I have used these chips for years on many brands of chanisaws, trimmers and engines. I have some wired up for testing purposes with alligator clips on them. Some chips do seem to perform better on some applications than others for some reason. I disconnect the wire going to the points and run it out side the saw case to attach my test chip to. Sometimes you might have to splice a longer wire on. Remove the plug from the engine, connect a new properly gaped spark plug to the coil wire and groung the plug to the metal case. I have a new plug with a groung wire soldered to it.. Connect the chip wires. One to ground, one to the wire that connected the coil to the points and make sure the chip case is properly grounded. Pull the rope and check the spark. It should be amazingly bright. If not, switch the chip wires around and try again. If spark is bright now, this is the way you want to connect the chip when installing it on the saw. The spark from these chips can be very bright accross a plug gaped at .025 and may not spark very well accross a conventional spark tester unless you have one with an adjustable gap. You have also tested the ingnition coil. If you have good spark with the chip most of the time the coil is good. You can either install new points and condensor ar a chip. I usually leave all the pionts harware as it was in case someone ever would want to go back to points. Sometimes if you have no spark just removing the coil and shinning up the mounting surfaces with emery cloth so there is a good ground can fix a no spark or weak spark problem. If I have a saw apart enough to take the coil or ignition module off I do and shine up the mounts and set the armature gap just as preventative maintainence.
You can ONLY use the chips on point style magneto ignition to replace the points.. There are many different configurations of these chips and prices.
This is just a little primer on these chips.

A few examples. Have used with good results

New Flickr picture of chips I use for testing coils and replacing points. Try them til I find one with best performance.

I recently purchased a Homelite XL 12 that has points,I was wondering which one of these 3 suppliers mentioned that supply modules would be the best choice to replace the points in my saw? Thanks in advance!

I have hade equally good luck with all three stlyles.
You may be able to buy them localy through a harware store, auto parts store orlocal small engine shop also.
Here are some other sources.
This is the one I use the most of.

Thanks for all the good information, I would be lost without all the good folks on H.O.H,in my small town the only parts and information at the one local hardware store is on that orange & white brand of saw. THANKS AGAIN!

There is already a write-up under Saw Repair Tutorial about these chips.

Just learned about these chips being available, so I found this thread at a convenient time.

Have you (or anyone) converted a magneto based 150 over to using one of these chips? Since I'm seeing them average around $20, I'm considering going this route. Just curious if there's a particular one that works best with the 150 and if there's an ideal mounting location in the 150's housing that'll provide best airflow to help with cooling.
