I have an Oliver 1650 diesel. I believe they came from the factory with two 6 volt batteries hooked inline, mine has just one 12 volt battery in it. Is there much differance in the differant setups? My Oliver needs a touch of either to get started (which I don"t like doing), wondering if I"m getting enough power to get the engine to spin and ignite the fuel. How much juice does the pre-heater take? Would it be better to have two batteries if I were to use the pre-heater?

Also, what guage battery cables do you all use? The tractor presently has light car cables. Thinking of upgrading to something alittle thicker this spring, but don"t think I need 00 gauge like what I put on my 6 volt Farmall H this past spring. Any help would be great. Rich

As noted on some of the replies; 2 - 6 volt batteries in series='s 12 volts is better than one 12v. It's the amps that you need and the bigger the wires the better but 4-0 ought to do it. Also noted one post saying that the bushings on the starter may be lazy and allow the armature to drag on the field coils. I have a Case 580CK with a diesel and use the 2 - 6 v batteries. Also the exhaust needs to show white smoke in cranking before the engine will start or some other fuel problem may be involved.

I had a 1655 that would not start at all until I was told to put a type 35 starter in place of a Delco 30 starter and that took care of my problems, batteries and new cables were not the porblem in my case.

You can make an external power unit by simply placing a new 12v batt in a weatherproof box (like a tuff bin) and keep a small trickle charger on it. Put the whole thing on a kids pull wagon and you can move it to where ever you need to use it. Don't let anyone tell you that won't work. We've had lead acid batteries set up that way for years. Just use the heaviest jump cables you can find.

Thanks for all the help guys. I"ve tried the pre-heater a few times this summer, but seemed to drain to much from the battery to start. I"ve never tried using both either and pre-heater at the same time, allways seemed like a dumb idea, but thanks for the reminder.

I guess I"m a bit confused on which battery setup to use. If I use two 6 volts hooked inline/ parallel, that would make 12 volts. If I hooked two 12 volts together, wouldn"t that get me 24 volts? Wouldn"t that fry the starter? Are my thoughts correct? The tractor has only one compartment for one battery, the other compartment either rusted off or got broken off. Unless I go to the junk yard and try to find the other battery box, I think I"ll just stick to one BIG 12 volt. I didn"t check yesterday to see how many CCA this battery has. Can any electrical shop check/ reuild the starter, or should I find a electrical motor repair/ rewinding shop? Thanks again for all the help, and Merry Christmas to all.

2 6 volt in series = 12 volt amps same as smallest battery
2 12 volt parrelled = 12 volt amps added together
should always use same size batteries most people recomend replacing together for max life
you can buy new battery boxes some people have reported very good results with the Optima gel batteries
fix it up so that you have enough amps to run the preheater and crank the engine. I have 2 6volts and preheat then hold the preheater and crank the engine at the same time. Works good for me. May need to take the starter in and have it looked at as I would like a faster cranking speed

good luck Ron

I still have the two 6 volts in my 1650. Changed the wiring out to 2/0 and it is too big. Probably will got to 1/0 then should be able to get the trim plate back on the platform. I used solder ends on the cables and hooked the batteries up in series. Have added the heater in the lower elbow have not tried it yet. Thinking next time I buy batteries to try 2 12 volt instead also changing the cables to 1/0 if not done before. Make sure all connections are clean and tight esp grounds. Car cables are too small for that engine
Good luck
Ron

All good tips but something else to watch for is to make sure the bushings and bearings in you starter are in good condition and I mean very good to excellent. Lots of times I've seen friends complain and belly-ache (spelling?) about their 6 volt system and after a starter rebuild 6 volt gets the job done fine. 12 volt systems also lose their efficiency, just not as noticeable.

The only thing better than AMPS is more amps. For my diesels 2 aught cables and group 31 1000 CCA batteries. Better starts, MUCH longer starter life. After more than four decades in upstate NY and sub zero temps a WHIF of ether should not hurt; not a blast, a whif. If you hear detonation you used too much. Have not hurt one yet. best, Yeoman

I use one heavy 12 volt in my 1650.If you can I would check your inmanifold heater and see if it works it is threaded in the intake also theirs a solenoid switch that activates it.You shouldnt use either and the heater together according to the book.

If 1650 Oliver has preheater or glow plugs- use them, the engine designer had them for a reason-mostly cold starts. Thick cables better than thin, if you have 2 battery trays, use 2 batteries- 12 volt bats can be wired parellel. IHC 560D and 350Ds need glowplugs and heaters used normally even moderate warm outside temps, 1650 probably same procedure. RN.

0 or 00 gauge cables with crimped terminals would be a vast improvement over what you describe. If you could fit a good 950 or 1050 CCA group 31 battery in it with new heavy cables, that should spin it over very nicely. Cranking speed is essential for cool/cold weather diesel starting.

At the risk of repeating, there is no such thing as too much (size wise) battery cable or too much battery. Light duty car cables are a definite no-no. If you could build a nice side frame, go with an 8D battery and heavy 0 cables as short as possible with the proper heavy connections. This costs a few dollars, but is way cheaper than an engine rebuild,due to ether ignition). Proper motor oil like 5W-40 and a good block heater also go together. If the tractor is parked outside or in a cold building, throwing a blanket on top to keep the heat is very helpful. If parked in the wind, a block heater might not be able to supply any useful heat withoyt the blanket. The wind will cool the motor as fast as the heater will heat. Just some ideas from 30 plus years of starting tractors in winter. QR

Merry Christmas to all.

Rich

2 6 volt batteries in series will serve you better then 1 12 volt battery. Install new cables,1-0 minimum size. 2-0 would be better.Make sure alternator is working properly.
Install an external tank heater to warm engine if you are close to a source of electricity.
