Pertronix installed...tractor not starting

I installed a Pertronix Ignitor in my 53 Jubilee today. I've used the Pertronix product before in my old Land Rover with excellent results.

After installation I went to start the tractor and only got a brief whine and click....battery was low. This was odd since I never had this issue before (new battery last year, 12V conversion last year).

I have the battery on the charger and I'll report back.

I ordered Kit #1244A.

Also, while working on the tractor I discovered several small wasp nest. Knocked them off only to have several wasps hovering for the remainder of the afternoon!

Paul.

If the battery is low.. don't count on the electronic module to fire..

The ford ignition system is easy to understand.Dont add extra crap that makes it hard to fix.

Actually the Pertronix is simpler than points/condensor set-up. It has no gaps to set, no contacts that wear out, and even corrects for any wobble in the distributor shaft caused by wear.

It also increases the strength of the spark. It has worked extremely well on my 1967 Land Rover. Basically, you install them and forget about them.

My battery is charged and in the next day or so I'll go back over to our land and report back on the performance.

Technically speaking.. it is not a 'simpler' circuit, electrically.

The points based system is a debounced switch that is mechanically actuated.

The pertronix ignition system is a transistorized solid state switch with supporting circuitry, including a magnetically tripped switch like a hall effect circuit.. for example.

Due to component content, and circuit design.. you cannot call it a simpler circuit.... Having even a single transistor trumps that argument.

I didn't call it a simpler circuit.

If you compare the number of moving parts and intermittent contacts between the Pertronix Ignitor system and the points/condensor set-up the Pertronix is indeed simpler...not even close. The design is used in many ignition systems. To go further the Pertronix Ignitor II system even has more corrective circuitry. As with most integrated circuits, if the system doesn't fail in its first few hours of operation then the circuit likely won't have a failure and will be fairly robust.

I stand by my comment that the Pertronix is simpler than the points/condensor.

It is by no means simpler.. The discreet electronic circuit jump it decades ahead in technology. Try, there are no moving parts.. but you can't discount the 'function' of each discreet component.

A fingernail file 'may' get you home if you have a points ignition and you encounter a problem. With an electron ignition.. that same fingernail file will let you file your nails while you wait for a wrecker.

Just because there is an electronic replacement to a circuit with mechanical components don't immediatly assume it is simpler.

The technology behind a set of points is simple spring, cam and lever.. that's something the greeks came up with. The operation and design of a doped npn/pnp or n-channel, or FET style transistor is a 1950's era brainchild.

The technology needed to make a set of points has been available for over a century and longer if the idea had been there.. the technology needed to make a transistor is just hitting the 50 year mark...

So I stand by my ascertation that a circuit requiring transistors is not simpler than one requiring a switch ( points )... there is a magnatude of difference.

Electronic ignitions that use an SCR cant produce a hotter spark than a point ignition.An SCR has a forward resistance of about 10 ohms.A clean point set will measure 0 ohms.Adding parts to device increases the chance of breakdown.I work with solid state timing circuits daily and they are far from trouble free.SCRs can self trigger and that would be a disaster in an ignition circuit.Ford Motor Co has had plenty of problems with intermittant failure of solid state ignition modules.There is a web site on Pertonix problems,check it out.

I have also done much electronic repair work over the years.

By a HUGE margin.. I have had more failures with solid state parts vs electromechanical assemblies.

My Ford 600 tractor has stopped running twice in 15 years due to point problems.Cleaning the points with a knife blade got it running again.If I had a solid state ignition it would have cost 200.00 to get running again.These ss ignitions are potted in epoxy so you cant see the few parts you have just spent 80- 100 bucks on.My 5.00 points were put in new 15 years ago.A simple cleaning and gap check once a year are all thats needed.My John Deere H tractor has run for 40 years on one set of points,2 condensers and a new coil.I dont need solid state ignition.The profit margins are very high for the companies that take 3.00 worth of ss parts and sell them for 100.00.

Yep. I've bot a box of points here on my desk. Most of my antiques are on at least 6 year old points... Most have been gapped, and cleaned yearly.. but some have just kept going without even re-gap.
