Gen output and aux lights

I would like to install (2) 35w off-road lights on the Haffy and was wondering if the generator had enough output to to charge and run the lighting.
Does anybody know?
Thanks,

The Haffy dyna starter only puts out 19 amps and two 35W lights will use almost 3 amps each.
You'll have to look at your total electrical requirements and see if you have 6 amps spare

Thanks Peter. How many amps does the ignition require?
Is there any way to increase the output of the Dyna?
Thanks again,

There are many examples of Haflingers with additional lights on the European forums. I would bet that 35Wx2 is within the operating parameters, but you would need to confirm that. I think that Dave Dunn runs his ARB Fridge off the battery, but I don't recall what wattage it draws.

I started out in Haflingers over thirty years ago but for the last twenty or so have concentrated more on Pinzgauers (even though I still have/love my Haflingers) so a lot of the details as to ignition draw etc have been forgotten in the passages of time
The thing is that you would need to work out the complete current draw for the vehicle to know if you are producing enough current from the dynastarter or if you are slowly drawing current out of the battery while the "additional" components are been used.
When you obviously run driving lights you will have the headlights on (possibly high beam), side lights, tail lights and of course the ignition and an accessories.
Years ago I ran a 24 hour 4WD event in the Haffy (fantastic experience!) but through the night we ran full lights (I have 55W headlights fitted) CB, map light etc and by the morning when we stopped at a checkpoint we didn't have enough battery power left to start again..... however I knew this was going to be a problem so I was carrying an additional battery for such an occassion.
I later hardwired a secondbattery in, with an electronic controller that does not allow discharge below a certain point, and while this "somewhat alleviated the problem as I have more storage capacity, in my mind it is a "patch" to the problem and not a fix.
Guys in Europe have fitted additional charging systems (I know of a guy who fitted a complete, yet entirely seperate charging system using a suzuki (?) alternator and components ....he mounted it where the governor usually goes) etc which is a good idea for just such occassions and one day I might look at this idea but for the time being Pinny's command most of my attention!

Thanks for the excellent information, guys. I'm planning on deleting the governor anyway.
Peter - Do you have any additional information on the alternator add?
Thanks,

I know of a guy who fitted a complete....
Hmm....I probably should have said, I KNEW a guy......
I haven't heard from him in 10 - 15 years, maybe longer, but somewhere I "should" have some photo's of the setup .... I'II start looking as soon as I have a spare moment.
I seem to remember he utilised an alternator from one of those small (almost tiny) Suzuki cars.... I remember the alternator was just like a full size unit, but small, just liked he'd washed it in Omo and it had shrunk

(I was tempted to get one and keep it, just because it looked so cute)

You're a saint, Peter. Thank you!
I have a friend that's into those Suzuki 4x4's. I'll ask him about an alternator.

It wasn't the 4X4 Suzuki, Mark, it was an 1980's version the little fwd/2WD car they make! .... it was like a little micro car.
I daresay any of the microcars "probably" have similar alternators etc.

Oh, ok. That might be a little tougher

Hello to all,
Several years back, we considered adding a small 12v alternator to one of our 24v Unimogs. We also have a John Deere 40hp 4x4 1070 tractor which happens to be of Japanese ancestry. It has the nicest little 12v alternator I have ever seen. I am currently out of town but will be able to get some dimensions in the next day or so. Seems JD wanted about $140 USD when we last checked on the price.
Hope this helps.
Take care.

Hello to all,
The JD 1070 tractor alternator has the following measurements:
OA depth: 3"
OA diameter: 4"
The diameter noted above does not include the mounting tabs. The 4" measurement also includes the cylindrical plastic shield which surrounds the actual alternator. I will contact our local JD dealer tomorrow to get a current price, part number and exact power output.
Take care.

Hello to all,
Here are the results of my call to the JD dealer
Standard alternator
P/N MIA 10338
Price: $267.75 USD
High output Alternator (35 Amps)
P/N AM 880339

There must be a less expensive option.
Take care.

Hope I'm not beating a dead horse here, but isn't this where a magneto like I was asking about on the Pinz side would work? I'm just asking because I'm still not totally clear on the whole deal. Just a suggestion.

Thanks for the great info. That's a pricey unit, but very compact. Should work.
