Napa 6 Volt Coil preference IC7 or IC7SB

greywolf224 · Mar 27, 2015

Getting close to completing a retrofit cover for a front mount to replace the square can coil.
Napa has the Echlin brand and a lower value brand 6v round can coil.
Anyone feel the extra $10 is worth it for the Echlin coil?

The extra money for the Echlin brand stuff is always worth it in my opinion. Most Echlin meets and usually exceeds OEM quality. Their cheaper line is no better than what you would buy at most any parts place selling cheaper parts.

Quality over Price always when it comes to ignition parts. Echlin is a very good brand when it comes to all of your ignition parts.

You don't want to be changing them out every year, or sooner.

An SB coil will work just fine.

Round can coils are not even remotely a common failure issue on n tractors.

I put an ic14sb coil on every 12v round can coil tractor I've used.

If I paid for the Echlin name it better have Echlin on it are a OEM
name... Standard ignition brought the Echlin name I have found some cheap parts in a Echlin box since they brought the name...

It would be nice to go back to when what you brought was just good parts instead of a choice... My local NAPA stocks the cheap chit you have to wait for the good parts...

Agree with you. My Napa also stocked the SB coil and not the Echlin. He said he had to look around for it and would take a few days.
Wants $19.98 for the SB coil.

Asked him for some copper core plug wire, he said "all the electrical wire we sell is copper core, no one has used aluminum fer years"...zoinks!!!! :roll:

Napa was out of my way so I stopped in to a local Advanced Auto and went in with the IC7SB p/n they referenced it to a BWD E5. Actually I see O'Reilly's sells it also.

The BWD E5 is a round can coil with an internal resistance of 1.2 ohms which I measured using 5 different Fluke and Beckman higher end meters to be sure. Specs are 1.04-1.27 ohms.

I need to replace the square can coil on a front mount with this coil to test out a conversion cap I have been building.

I am thinking that if I by-pass the OEM dash resistor I will be sending ~5 amps across the points. Am thinking to leave the OEM resistor in line to limit the current further. Only issue is once the OEM resistor heats up I may be limiting my current too much.

Am I over thinking this?
