HI, I have a 1920-ish T ford, just got her, wondering if I can use a 8 volt battery, other jobs I have used them and they worked out swell. I know I may have to tweek the cutout or change it.I don't want to do damage to the other systems. I took the pan down to inspect things in there, all looks in great shape only there are no dipper's on the rod caps. the engine looks to have been used a lot. and the rod's are snug and have shim's in place. any advice here? thank you Greg

yes 8 volts works great. The Gen. will still charge it.

No dippers are no problem. Ford built 15 million T's without them. Dean Yoder has put many thousands of miles on his touring which has no dippers.

It's a popular superstition that you need more than six volts to start a Model T. Not true.

Richard, you may get brighter bulbs - but you would also get extremely short bulb life, less than 1% of normal life for a 6V bulb with the engine running and the 8V battery getting charged. See John Regan's answer in this older thread: http://www.mtfca.com/discus/messages/179374/200309.html?1301172455

I would make sure the reflectors are clean and with good silver plating, then check so the bulbs are focused and keep the 6V. When driving at Model T speeds, I can see the road well with my 6 V headlamps.

There's a real danger getting rear ended by modern drivers when going at T speeds, so it's important to have more than one rear light - and bright ones, too - the old kerosene lamp isn't bright enough for today's roads, unfortunately

Grandpa swore by 8 volt batteries in older tractors because it would spin the starter faster. I suppose that makes sense when your tractor has a magneto ignition, because faster revolutions create a stronger spark and should start the engine faster.

After going to college (oh boy, here we go with this stuff... haha) I've learned why people started putting 8 volt batteries in 6 volt systems. Usually the terminals and connections begin to corrode with age, and this corrosion creates resistance. The extra two volts in an 8 volt battery will make up for the voltage loss due to resistance, so the system is "fixed." If your old car or tractor is experiencing a voltage loss, spend an afternoon cleaning as many connections as you can find. Especially on the starting and charging systems. It can make a world of difference. And it's cheaper than buying a new battery.

If you really want to run an 8 volt, I'm not going to tell you that you can't. It's your car and you can do with it whatever you like. But I agree with Roger, in that you'll burn your 6v bulbs out faster putting 8v to them. Unless the connections to them are corroded as well, which means your headlamps won't be any brighter than they would with clean connections and 6v.

As for the rod dippers, I think they give the owner more peace of mind than actual improved performance. I haven't seen anything that says an engine with dippers runs any better or any longer with them than one without, but that's not to say nobody has tested it.

Again, these are just my opinions and you're free to do whatever you wish to do with your car.

Jared, ive been a Grandpa for 45 years, and installed many 8 volters in model-a's Stutz- 2-n's nash's I found brighter lights in them all, just needed to tweak the regulator to up the charging a bit. and yes the old starter woke up and there was power leftover for the coil too. what is the difference in those head light bulbs and the t's.? I guess im going to wire up one of my old Mazda's and see how long it takes to go dark. now onto something a little different, the 1920 ford I just found has two types of wheels, the front has wood fellows non demountable the rear are demountable with steel fellows,will they both take 30x3 Tires? why do some rears want 30x31\2 ,how do I tell the difference?. and why? MODEL-T-IS SHURE A LITTLE DIFFERENT! thank you greg.
