Onan Electronic Ignition for the 6.5NH 

Cool man

THIS IS HOW I FIXED MINE, IN THE CASE OF.... "I CAN'T START MY GENERATOR" It's has been two years since last time it was running, so I started by checking oil level full at gen dipstick (it won't start if low oil because of sensors) then I checked gasoline more than 1\4 tank in the RV (also safety sensors), sparkplug checked for good spark, also checked the manual reset circuit braker ( to be ON) at front motorhome engine compartment for 12v current to the generator to be able to start it, also cleaned the carburetor and even installed new one but same situation, then checked wires and found some has been chewed like gum by rats at the back of starting switch generator panel so I replaced them, at this time the generator started but stay running only by keep pushing the switch on all the time, so then finally I knew it was internal electrical problem from the engine itself, so I took the generator out from my RV to work in my garage, (I did this by myself with some tools and old Mayan tricks ) lol, it's really heavy for one person. I disassemble the unit at my garage and started by removing the cover, then the cooling fan or flywheel unit (it's 2 items in one) until finally I was at the gen rotor and brushes assembly area and this is what I found: one more wire chewed by filthy rats plus the stinky rat nest in the middle of the generator motor coil, I fixed the wire and sanded the commutator copper contacts where the brushes are sitting becouse they were real duty with old urine from the rats, and of course I got rid off the stinky nest, lol!!! Then I assembled everything back together and... bingo it's runing like a champion!!! For this project materials involved was about $60.00 including an aftermarket new carburetor and an harmonic balancer/steering wheel puller (available at any auto parts for $25.00) to pull the aluminum fan out and (flywheel). Just picture this: (Any gasoline engine run smooth if gasoline and DC current aren't interrupted) so following this important principle you'll always find the problem to be fixed. Also if you have a onan microlite 4000 like mine, don't run it for more than a minute without the cover because you'll cook the engine real fast, also keep the eye on the aluminium fan and your fingers after cranking it in case you missing one or two members...just kidding, lol!!! After testing the gen with the help of a gasoline container, a piece of hose and 12v battery, I did put the air cooling assembly back and the rest of components including the cover, then it was ready to be installed at my RV. Once the gen was installed back at my motorhome I started it to be tested for 120v electricity but not before flipping the AC circuit switch (on) at the gen starting control panel (sometimes hiding under or around the panel) to be able to transfer power to my RV GFCI main outlet and electric panel as well, my motorhome it's equipped with GFCI so I reset it and tested for green led light indicating power is ready at my main breakers panel, so I turned my main breaker (on) along the others ones but no power was present at my breaker main switch (faulty main braker) so I flipped it many times, sometimes you can make it work again, mine did work, lol!!! I'm happy because everything works now including the refrigerator for cold drinks and AC for this crazy summer, lol! Later I'll buy me a new main braker, for now this is a resurrected generator story that needed to be shared. If this can help eaven one person to save time and $$$ it'll make me more happy, thanks for reading!!!

For a pushrod-type Onan system (with points), like the 6.5kw you have, you can use the points to trigger a single transistor which will then trigger the HEI, so you do not have to install a flywheel sensor. It's 3-4 parts (a single resistor is the third part, with a heatsink for the HEI depending on where you mount the HEI), and it costs about $30 to $45 to build [Heatsink if you need it, HEI, 2N5302 power transistor, 1x 4.7Kohm resistor] The video is on my channel, "How to add HEI to any points system with 3 parts and keep your existing points." Because the points only have to trigger a transistor, and the power transistor does all the heavy lifting to the HEI which in turn fires the coil, they handle infinitesimally small amounts of current, and 1 set lasts virtually forever. When connecting the HEI circuit, disconnect the condenser because you won't need it, and back the dwell adjustment screw off 1/2 turn, to compensate for the timing delay introduced by the transistor+HEI circuit. I cover that in the description on the video.

Hi, did the 6.5 NH have the mounting holes for the T260 trigger? Does the trigger rotor just press on the crank of the 6.5 Nh ? How do you time the 6.5 Nh with the T260C ignition setup? Thanks Jim

Excellent setup. I have one of these gensets in my motorhome unfortunately it does not start as easily as yours. The motor shakes violently side to side on cranking smooths out once running.

Where did you get the muffler for that Onan 6.5NH?

Have same unit, not getting current to coil. Maybe a relay that is below the starting solenoid???

im having a problem with myn it wont start or shut down with the switch. i can jump it off and run fine checked the switch all good. everything checks out good.

My Oman not getting any sparke from the sparke plug can you help me with the probably it the 250 amp

Saludo tengo un generador de eso me puede mandar el diagrama de encendido de una por favor
