45 hp Chrysler magento ignition questions

[chrome dome]

G'day,
have a 45 hp Chrysler with magneto ignition ( '74 model, electric start ) bought as a non running project motor, on a stand
changed plug leads around, started and ran several times, went away a holiday, came home couldn't get it to start again, pulled flywheel off again, points weren't opening now, adjusted the old points but spark isn't real "flash"
now the questions..
reading Chrysler Crew manual ( have Clymers/seloc as well ) it says this about routing the coil wires " lead wire ( top one? ) next to HT wire to breaker points...Lead wire on bottom half of coil to mounting screw on breaker point"
(might not have that word to word but close enough )

that is different to how it is wired now, top coil lead goes to the condenser mounting screw and bottom wire goes to the breaker points, but not the mounting screw,
the top wire just isn't quite long enough to be attached per the CC manual but can just touch the the point screw,
which one is correct?
coils are under the flywheel,

also will the condensers off a Battery ignition 45hp work on a magento system
".. .. .. .. points of a battery ignition work.. .. .. ..on a magento .. .." or are they too long?..look longer, haven't taken them off yet

also, l can't get a test light to work doing the spark control link test, screwing the lock nut in or out several turns, have undone condenser etc etc
ignition switch does not show continuity between B and S terminals ( as in Clymer/Seloc manual ) however l've done the same test with two switches and it's the same,

is that a reliable test?
could it all.. or just some of it.. be related to a dodgy switch or a dodgy tester ( me )
one last question, standing at back of motor looking to the front, the coil on the left side is for No.1 cylinder?
BTW,
also have cleaned but not rebuilt carb, have tried a good carb from another motor on it, no joy there
cheers
thanks for any or all help
sorry for such a long post

Re: 45 hp Chrysler magento ignition questions

inside of point followers are badly worn, battery ignition points won't work, too long

and, nope..the Battery condensers didn't work either..
woe is me

Re: 45 hp Chrysler magento ignition questions

While it looks simple, the magneto is actually quite a complex piece of work. Because of the nature of the iron core and the windings, It actually delivers an AC voltage. Part of this voltage is absorbed in the condensers. That's a real simplistic description so don't come down on me. The points make and break the current generated by the magneto in the primary winding. SO: One lead of the primary winding should connect to the insulated terminal on the point set and the other lead should be grounded. Additionally, the grounded lead must be the one that is siamesed with the high tension (secondary coil windings --fine wire.)This wire is usually short and is usually attached to the iron core very near the coil.

Points need to be set to .020 open. Condensers are grounded by the mounting screw and the center wire is also connected to the insulated point terminal.

As far as the ignition switch: The run position "I" is not used except for instruments. The battery and start terminals will only show continuity when the switch is turned to start, just as the battery and choke will only show continuity when the key is pushed in.

The two "M" terminals are the stop circuit and the two brown (usually) wires that look like lamp cord are attached to the insulated points terminals and the two "M" terminals on the ignition switch. These two terminals will have continuity only when the switch is off and short the points together, stopping spark..

Coil for number one cylinder? Ahh--I don't remember. I would need to go down to the garage and look at an engine--not an easy task finding one disassembled with the magneto plate visible. HOWEVER: I am sure that they are ALL in the same position for all Chrysler 2 cylinder engiones. The coil for the top cylinder on your battery ignition will be the same (position) as the coil for the magneto ignition

Re: 45 hp Chrysler magento ignition questions

thanks for replying Frank,
your description of how the coils/condenser/points are wired is the same as how the plate is wired, so that's good..
simple is good coz according to my wife l'm,.. well l won't go there..LOL

points are at .020 and condenser wires are as you've said,
ignition switch is wired the same and B and C are good,

the one thing that isn't as you've described is that the 'lamp cord' wires ( other 45 has them though ) on this have been replaced at some stage with joined black wires from the terminal bar, but they have continuity from the switch all the way past the TB through to the points,
l think the points and condensers need to be replaced anyway so will order some soon ( cost more than l paid for the donk! )
one other thing, after more testing ( ok, thats BS, was accidental LOL ) found that one of the magnets inside the flywheel has lost its mojo and float pins won't stick to it when its used as a holder for widjets and thingees,
tried other flywheel briefly, no go don't know whether that is a good idea though, 4 magnets compared to 2 may be too many" herbs",
anyway, thanks for the help yet again,
cheers

Re: 45 hp Chrysler magento ignition questions

The points and condensor "tune up kit" is quite expensive. Try going to a local auto parts house and look up part # FM200 for the condensors (thats what it is at my local U.S. NAPA auto parts store) . The points will be murder on the pocketbook to get to you but unless you can clean the current ones I think its time to bite the bullet. At least that is... until I can find a suitable cheap crossover auto set and I will report back if I ever do.

Re: 45 hp Chrysler magento ignition questions

thanks for the part numbers tater76,
l'll have a squiz and see if they're the same here, when l can get to a decent shop ( live in a two pony town )
yep, the kit if bought over there is gonna cost me $111 AUD, l'm not quite ready to pay that yet, the donk only cost $50 but if l can't find it local at a reasonable price.. haven't been able to ask around yet.. that may be the only option..

unless l can do something like this ( l knew it was a good idea to save it LOL ) it is after all a project motor..and that is a project LOL

Re: 45 hp Chrysler magento ignition questions

Not sure if a 55hp flywheel would fit but I have a good one if you need. Also, if and when you go to the autoparts store take the points with you. Often thats what I do here, and the fellas behind the counter can match them up the the closest thing. You might get lucky and end up paying half of that $111. Another option is rob the ignition of a newer style electronic ignition motor, and do the swap. That is of course if you could find a cheap as dirt blown motor.

Re: 45 hp Chrysler magento ignition questions

Tater76, thanks for the generous offer of the flywheel but l should be able to find one around here, if needed,
yeh, did that match up points years ago with my 80 series landcruiser ( early one ) when points went on it, just to get home late at night
just tried it again at the closest auto shop, no joy there but now have to concentrate on getting a car repaired after whacking yet another 'roo..
stoopid beasts..
thanks again for the help
