JUBILEE ISSUES

Well I am having some issues starting my 8-volt jubilee. Battery was just trickled charged for 8-hours and still does not seem to ever be reliable. Any sugguestions about converting to a 12-volt system. Seems like it would be a lot easier than puliingout the battery to charge. Any thoughts on converting to electonic ignition ??

Some are against changing to 12 volt system. Some that do change stick with generators so it looks more original. Changing to a 12 volt alternator gives a very reliable system which will support the use of lights and other modern stuff you may want to use. It also lets you easily jump start to or from the tractor. The hardest part of the changeover is mounting the alternator and sometimes coming up with an appropriate pulley to match the belts on the tractor. I think the belt on your tractor is not the old wide one. I change my stuff to alternators.

8 volt battery's are at best a band aid fix for other problem. Cost to switch to 12 volts can be less then $100 including the battery.

Be sure to check the liquid level in the battery cells if below the plates fill to the appropriate level. charge then let it set a day and check state of each cell with a battery hydrometer. It'll will tell you if you have a bad cell.

How old is your battery?

Having a bad cell isn't worth changing it to 12 volts in my book!

A jub is one of the Easy ones to convert to 12V,,, most of the naysayers are just skeered to make their tractor better or ride'n the skirts of other 6V nutz

6V works fine around here. The engines are maintained, carbs clean/setup, ignition up to standard. Real 2/00 battery cables not Wal-Mart bargain bin 4 gauge junk and a high CCA battery.
12V conversion are too often a bandaid fix for worn out and poorly maintained equipment. Too many people rush out to treat the symptom rather than the cause.
Ever count the number of posters here trying to connect a $49.99 napa alternator for a cheap easy fix?
For something so cheap simple and easy there are a lot of smoked alternators, burned points, failed ignition coils, non functional instrument gauges, non functional lights etc.

B&D,
You seem to be knowledgeable about a lot of these old systems, so have you ever heard of partial charging an 8 volt by using it as a 6 volt (3 cells + one post{pos or neg
}, then the other post and 3 cells. Seems that I remember something like that when 6 volts were the standard and 8volt was the common fix.

A 1/2 charged 8V battery doesn't crank as well as a fully charged six volt battery.
Batteries fail rapidly when kept in a partially charged state.

The ideal charging voltage for a V battery is 6.9V in warm weather, 7.1V cold weather.

The ideal charging voltage for a 8V battery is 9.2V in warm weather,9.5V cold weather.

The ideal charging voltage for a 12V battery is 13.8V in warm weather, 14.2V cold weather.

Problem is the ignition, lights and electric instruments if so equiped. They will over heat and fail or be inaccurate when subjected to 9.5volts.
7.1V from a 6V charging system into a 8V battery will keep the ignition system going but the battery is going to discharge into the useless range.
A primary problem with operators on generator equiped equipment is that they won't rev up the engine. And the voltage regulator was set by looking at the ammeter instead of measuring at the battery with a VOLT meter.
A 12V alternator charges at 13.8 to 14.2V by default and suddenly solves low battery problems. If the generator's regulator was dialed up 14.2 most charging problems would go away as well.

$100 Bucks? Any ideals on where to purchase for that price? I assume the would not include the alternator?

EDNEWBOSTON · Jan 2, 2009

Should I fill with distilled water if needed?

I probably need to go over to Harbor Freight and buy a hyrodmeter. Don't have one.

Any other ideals to test for the battery? Sorry I am new at working on a tractor and not to mechancially inclinded, but I am trying.

Thanks all for the replies..

In my area an alternator from O'reilly's auto parts store is $35 plus a core which I always have laying around $45 with out core and that is with a life time warranty, Battery another $45 or so then the wires so cost is right at or under $100. I do all my own wiring which isn't all that hard to do

Don't over fill the battery. Acid will slobber through the lids and corrode your tractor.
Good to hear you know enough to use distilled water. Most people use tap water and wonder why battery life is short.

Sorry but I warned you that I was not that mechanically inclinded. I have a volt meter would I switch it to 1000 DCV to test the charge?

This is a postive grounded battery.
