Default Onan 6.5 NHE Electronic Ignition upgrade

As it says in the title, I have an Onan 6.5 NHE Spec "A" & I want to upgrade from points to electronic ignition. It does have what I believe is the "newer" points tower. Fairly easy access on top of engine. I've heard that I will need that base plate for the electronic conversion, correct?
What else I have gathered, I need pn 160-1376 which is the Electronic Ignition Kit. Now do I also need a different plunger as well as a new gasket? If so, are these the correct parts number? 160-1151 Plunger & 160-1368 Gasket.
Greatly appreciate any input.
John

Better B sitting down when you price that kit out... Unobtainium, and you're gonna bleed!

Uh...i have priced it out & from what I have read what other guys paid to do the same job, I can do for over a $100 less.
What's this "you're gonna bleed" crap. Maybe I should have written constructive input.

What he meant was when you see the price your going to die as if you've been shot and are bleeding.

Think Onan's electronic kit for use with points is ~ discontinued. Anyone that has one prices it as if it was made of solid gold. Unless you get real lucky.

Since you have the NHE maybe your thinking of the electronic pickup modual ~ $95 and PLASTIC magnet arms $30 that are used on later spec NHE's . I wouldn't go that way since the PLASTIC arms like to break if mouse nest, mud wasp. Maybe it would be ok if you tried putting the magnets in the flywheel instead.

Thank you for the clarification. My apologies for being overly sensitive.
Cheap, they aren't. The kit plus plunger & gasket are about $170. I've heard people pay almost $300 for everything. If it will make it start easier & run smoother, I think it will be worth it. Not happy about paying that much but less happy with the way it runs when it runs.
Thanks again & sorry for over reacting.

As already stated, the kit has been discontinued. If you had just a 6.5 NH (without the E) I could tell you how to add electronic ignition that would be cheaper and better (in my opinion), but would require work. Since I am not familiar with the Emerald version I don't want to steer you wrong.

I gave some thought to using a coil pickup and ignition modual from a car for my JB. Some stackers have posted threads on how to do this. One that I can remember is named ~ Bobby or bobby Z.

The method is basically the same for all engines, only question is some of the old engines like NH ?? ( not NHE) use 6 volt coils (so you use a series resistor with coil). Pretty sure all NHE /BGE use 12 V coils , look at wiring diagram. Not really much difference between car ignition and NHE, JB, or any other battery powered coil .

Thanks Len, I probably should've elaborated a bit more. Just trying lighten the mood when the OP finds out the price... I'm lucky I scored mine reasonable, though I haven't used it yet. Just not sure if I want to commit to a spendy setup like that. Pertronix module itself is still made for ~$100, just need to buy a kit and ...extract... the module and transplant it - if original -1376 module croaks. Don't know if Pertronix would sell a raw module.

Yeah, kit is cool but I guess I'm more of a practical dude...

Think the old Chevy ignition moduals are $50 new , Maybe $5-10 in a junk yard used.
Need a pickup coil too , but can also wind your own or salvage a coil assembly from a relay.

Here's link to just one use of car ignition moduals.I think the staker with good ignition designs was Bobbyz71 ??

I have done this mod with GM modules. Ford modules are even easier. You have to remove the condenser. I have a diagram for conversion. I use the cheapest modules I can find done cars outboards ect going to do my Onan bf as well.

The points are used as a signal for the modules only very low current milliamps.

The theory behind all modules is to increase the voltage going to the coil to around 500 volts on the primary side high voltage low current. This increases the secondary voltage capability to fire the plugs. Therefore, you can use an 8mm wire versus a 7 mm wire to the plugs plus increase the spark plug gap. All ignition coils all are limited by the internal wirings to increase the primary voltage to higher secondary voltage, hence increase the voltage on the primary side.

On the signal side of the module you only need milliamps current draw to fire the module, this allows the points last. The only maintenance is to lube the plunger or cam.

On my Mercury outboards I have duel point distributors that I use from donor motors. Mercury module and trigger $ 650 .00 vs $60.00 for GM conversion
