8n front mount 6v, would it damage anything to try to crank start this tractor using a 6v
half wave battery charger as supply for ignition? Thanks

boler.......not certain what you mean by "crank start"? Do you me "armstrong starter"? in the notched ratchet NUT on end of crankshaft? As fer the half-wave charger, will it supply 5-amps? ........BYTE the BULLET, buy a REAL 6-volt acid cell battery and fergitt all the fancy stuff. Reminder, when you replace the points (0.015") remember to "polish" the INVISIBLE corrosion from between the points (0.015") Me? I clamp the corner of $1-bill between the points and pull. Simple, eh? .......Dell, yer self-appointed sparkie-meister

are you trying to run the ignition solely off a charger vs a battery?

If so, maybee/probably yes, if the supply can handle the ignition current, however, the problem you have is when point sopen, the circuit unloads and voltage can go high. most half wave basic dumb chargers have little to nothing in the way of voltage control, and simply rely upon the secondary of the transformer to close match output voltage, that in account with intended charge rate as a load, and in general, a simple tyransformer and single diode charger, will usually overcharge a battery if left on too long, due to lack of charge regulation, and as current load drops, voltage goes higher.

will it work as a test? probably, depending on your charger. will it make the points wear faster? I would think so, yes.

in reply to Dell, I mean by "crank start" is to try to start the engine with the crank, my charger is rated at 6 amps, if I could run down the street and buy a 6v battery I would but the ones down the street are too far away and I want to try to start this engine to see how it runs before doing any more repairs thanks for input

 

[souNdguy]

put the charger on the battery as long as it doesn't have a shorted cell... it will provide some load for the charger, and as long as not bone dead, will filter that half wave.

a BIG capacitor would do the same..

boler........yer makin' MORE WORK fer yerselfs by bein' CHEAP and refusing to byte the bullet and buy a real lead acid battery. ........respectfully, Dell

 

[boler76]

so what about using a 6v sealed beam and hooking the tractor ignition up in parallel with it?

 

[boler76]

thanks for the compliments, they sure do make a tractor run a lot better, I had a hen once that didnt lay eggs till I complimented her on the nice stance she took hovering over the nest

 

[souNdguy]

ideas are getting absurd now...

Was to a yard sale over the week-end. WIDOW's 3rd husband. I bought that "CORP. BLACK and DECKER9tm" belt along with the brass buckel. All fer $1.00

She, the widow, says to me "One of these days, I have to have an audit of the MEN's STUFF. I says" I am in the book, call anytime, even 24 hrs. a day".

Makes sense to me. I once had a Banty hen that wouldn't accept the brood of Rhode Island Red chicks until I did a one by one introduction and spent half the day parading them around with her.

I would try the charger and the hand crank if I had nothing else. If the battery is toast you will do no harm. I'm thinking it won't work, though, and would plan on a good battery. Eliminates one variable.

Aw heck, hand crankin aint so bad, as long as you do it right, have fuel n spark, and it's in time. Might wanna wear a good winter glove though, dem blisters smart.

 

[Royse]

Do you have a battery in it at all? If so I would try charging
that battery up, leave the charger running and try it.

If not, it most likely will not hurt, but may not work.
Batteries are expensive, but necessary to run the ignition
on a distributor fired system even if they won't spin the starter.
A tractor with a weak battery can be pull started for example.

If you had a magneto fired ignition it wouldn't be an issue.
Just don't give one of those too much choke!

If you just want a 10 second test, use a 12V battery.
Need more time? Add a resistor in line with the coil and disconnect
the generator/voltage regulator so it isn't trying to charge.

gotta love a true sense of humor.

lol, good thread
never know till you try.
put your spark checker on it, hook up the charger and give it a crank. see spark?

There are some rich fellas here....I'm like you....spend $100 on a 6-volt battery to test stuff?
hahahaha...not a chance.

hmm...here...if charger thing didn't work...ok, truck/lawn mower/whatever...jumper cables and some alligator clipped wire should get me some power to that coil.
not an original showpiece eh? ok it'll be 12v then here.
I see a lot of posts on batteries...bought $ and designed for giant diesels I think.
The most pathetic cheap little lawn tractor battery will run, crank over (if electric start) these wimpy little engines.
(strapping on one of those cheap jump starters works good too on a tractor with no battery...looks a little silly though )
