I'd replace both coils under the circunstances. Possible bad power pack.

Re: 77 25hp rude coils

I would go OEM or CDI. As mentioned above, change them both as a pair.

Re: 77 25hp rude coils

well still no spark on #1 after new coils Why didnt i order a power pack when i ordered the coils anything else to look for? should have done a better job testing things out F R u had it right but #2 coil is not arcing now so probable not a bad investment on the coils they look like original.... thanx Larry

Re: 77 25hp rude coils

An arching coil may easily kill the powerpack.

Re: 77 25hp rude coils

#2 coil was the coil that was arcing and blew out #1 side of the power back does that make any sence Hman? no matter need new power back agree??? probably order 1 tomorrow waste $10 shipping dang!

Re: 77 25hp rude coils

Arching coils may send 25++K Volts into the primary of the powerpack and then it is goodbye!!

It normally blows out a 10cents diode if you buy it at Radioschack, but a bit 'tricky' just to replace as it is all bedded into epoxy!!
