Cb 500 coils

[gary123]

In the copious amount of "stuff" I got along with my recent purchase are 4 sets of coils.
They all read 0 ohms when tested so I'm either doing it wrong or they are all scrap.
I dont want to buy used off ebay cos they will probably be the same, so can anyone recommend a source for
new ones or does anyone have some spare for sale.

Are you using the kohm scale if applicable. Having learnt the hard way!

[gary123]

Pretty sure Im doing it right. 200 range for primary looking for 3-5ohms, 2k range for secondary. looking for around 10k.

It would be very strange to find that many duff in one place, i havent seen an electricaly duff one ever, physicaly damaged yes

[gary123]

Thats what I thought, might give it another try.

Have you looked in to replacing the HT leads. There is a post by Ash on how to do it and the test. Maybe in Ash's drop box 

[gary123]

OK ill look into that -Thanks

I would definitely look into ashs method for repairing them and replacing the leads at the same time.
I had the same issue as you and with a bit of trepidation followed the repair route, but it worked a treat and you at least then know you have got a fully functional pair of ignition coils.
