SPI Coil 01-143-19 Specs?

[mssacs]

Anyone have any idea what the primary resistance ohms are on the SPI replacement coil?  (model 01-143-19) Many vendors are offering this as a direct replacement for the original coil on the 1980 SS440 Invader.  I get 0.8 ohms on the 2 primaries to ground while the Kaw manual calls for 0.37 +/- 20% ohms.  (One VTOM shows it as 0.9 ohms.) Trying to figure out if I got a bad coil or if their "replacement coil" disregards the original specs.  If others have the SPI replacement coil and it also shows 0.8 to 0.9 ohms I will know.  I had some concern about the higher resistance straining my CDI box.

Welcome to the site!!  I have no experience with the SPI coils but we have several guys who might.

Did you zero out your meter before measuring the resistance?  Most meters will measure .3 to .4 ohms when shorting the leads together.  This is the resistance of the leads themselves and the connection points.  This would explain your .8 to .9 reading you are getting.

Excellent reply on zeroing out the meter - I always read the leads on a higher scale so it did read zero on the leads - when using a low ohms scale it reads 0.4 ohms!

Question solved.  Appreciate the replies.

I'm glad all those years working as an Electronics Technician are good for something!  LOL  I'm glad you got it figured out.
