Fat Dan 114 Posted November 28, 2019 Share Posted November 28, 2019 (edited) Ok. Ok, ok I know another question about magnetos and coils. I have looked here, there and over there too but I can't seem to find the any specs on my IH H4 coil resistance. Anyone know what the acceptable ohms between the primary leads? And an acceptable ohms reading between a primary lead and the secondary lead? Well poo!!! my 1980 something ohm meter just took a long walk off a short pier.

12_Guy 955 Posted November 28, 2019 Share Posted November 28, 2019 I could test a new one in the morning, but it may not help. It could test ok and still fail when hot. My suggestion would be to replace it. It looks pretty old. Possibly the original. 1 Quote Link to post Share on other sites
Fat Dan 114 Posted November 28, 2019 Author Share Posted November 28, 2019 Ha ha that's the newer one that came out of my T9 which had a TD mag. The one that came out of the 46 Adams was dated 7-44 but it has no continuity in the secondary winding. 😯 Quote Link to post Share on other sites
Fat Dan 114 Posted November 28, 2019 Author Share Posted November 28, 2019 I'm thinking your right about buying a new coil. 😕 the 003 ohms I bet is too low. Wonder where a guy could pick up one of them bad boys? Quote Link to post Share on other sites

12_Guy 955 Posted November 28, 2019 Share Posted November 28, 2019 Rustic Red Acres, Alderson Tractor, Steiner, Standard Magneto. All seem to be about $60. All look the same. Probably all made in China. 1 Quote Link to post Share on other sites
12_Guy 955 Posted November 29, 2019 Share Posted November 29, 2019 I checked a couple of new coils today, they tested similar to yours. 1-2 ohms on the primary and 11k-13k ohms on the secondary. I had a couple of old ones that tested similar but were removed from service. Quote Link to post Share on other sites
Fat Dan 114 Posted November 29, 2019 Author Share Posted November 29, 2019 WOW! Thankx everyone I would have never checked NAPA for a coil. I looked for a condenser at the local NAPA, several years back, but the kid behind the counter was lacking the knowledge of condensers. God said treat others as you want to be treated, yes Lord I agree but I must add - Ya just can't fix STUPID! 😮 Was that in my out loud voice. Price is not too bad if you need to plow a foot of heavy sloppy snow/slush out of your driveway Quote Link to post Share on other sites
