Rusty_OToole Posted February 5, 2023 Share Posted February 5, 2023 This came up in reference to the Cushman magneto thread but I thought it best to start a new topic. The idea is, you need to recharge the magnets to make an old magneto work its best, this goes for early cars magnetos as well as small engine flywheel magnetos. I ran across this video on how to make a magnetizer if you can't find an auto electric shop to do it for you. It only takes a few minutes and the local auto electric shop used to do it for free, but I know there aren't many old time auto electric shops left. So, if you are working on small engines and magneto equipped motors this may be the answer. 1 Link to comment Share on other sites More sharing options...

pnaletruck58 Posted August 15, 2023 Share Posted August 15, 2023 Current (early Sportster) and former (Triumph and K Models) magneto fired motorcycles often have issues with weak sparks. This 'grass roots' approach is greatly appreciated! Link to comment Share on other sites More sharing options...
Akstraw Posted August 15, 2023 Share Posted August 15, 2023 (edited) There are several videos/articles out there on using rare earth magnets to remagnetize a magneto. Very inexpensive and easy to do. I made a remagnetizer for about $30 in materials. Here is just one take on it: https://www.google.com/search?q=magnetize+magneto&ie=UTF-8&oe=UTF-8&hl=en-us&client=safari#fpstate=ive&vld=cid:ef732ae7,vid:pqq4dqsDz70 Here is the article I followed: https://www.gasenginemagazine.com/equipment/implements/build-magnet-charger-zm0z22amzram/ Edited August 16, 2023 by Akstraw Added info (see edit history) 1 Link to comment Share on other sites More sharing options...
dodge28 Posted August 16, 2023 Share Posted August 16, 2023 A simple way to magnetize is to coil wrap a piece of magnet wire around the piece, hold one end of the wire to the battery post and scratch the other end of the wire to the other battery post . Scratch one way only . Not back and forth. The power of the magnetize piece depends on the number of coils and the voltage of the battery. Only DC current works.
