|GMCTRUCKS||My brother has a 8 volt battery on his 6 volt VW all he did is turn up the generator it helped a lot for night driving.|

Sort of of on the subject of batteries. This maybe common knowledge but i top mine off with distilled water once a year.
i got 12 years out of a battery until i gave it to my stepson. I thought the battery was bad but turned out the bearings
in the starter was the issue. Dad will replace a battery when the warranty expires. I will push one until it crokes.
I have AAA.

I'm getting a 6 volt Trabant and I'm considering converting it over to 12 volts just so I can use "off the shelf" components like H4 headlamp bulbs, FM radio, etc..
Otherwise if I need 6 volt bulbs I'm going to have to order them over the internet. Never seen any at AwfulZone or Advance stores. NAPA? There is a light bulb store in Bristol Tennessee that claims to have all your lighting needs and may carry 6 volt automotive bulbs. Hate to drive 30 miles for a lightbulb.
I assumed R2 6 volt headlight bulbs were dimmer than 12 volt H4 headlamps. But several Trabant owners say the lights on a post 1983 12 volt systems don't produce any brighter headlamps and the reason for the chnagover to 12volts was because they added a rear window defogger in 1984.
The seller informed me the battery is weak and may need to be jump started when it arrives. So I went to Tractor Supply and picked up a 6 volt with 625 cold cranking amps. Didn't think I could buy a 6 volt battery at an automotive store.

Damit!!! Instead of spending $90 for a 6 volt battery. Im just going to invest in a Rebel Wire 8+3 kit for $169 and begin the conversion to 12 volt. I dont care much about the lights etc.. Im just interested in getting the car running to test the Engine and transmission.
Soon ill be inquiring as to how to change the coil, points, alternator etc... to 12 volt.

|EOD Guy||Just about everything uses 12v nowdays..... most battery supply stores can order you a new 6 volt.|

Most motorcycle batterise probably won't have enough Cold Cranking Amps, 40 years ago batteries were built differently, they were put together with melted tar, there were small shops that would drain out the acid, melt out the tar, take out the plate assembley, wash it off , clean out the sludge in the bottom and if the plates and separators were still good put it back together and melt tar back in. and sell you a rebuilt battery.. they usually would last 3 years max. recycle the old ones and invest in a new 6 V

|67Elcamino||Is there any way of knowing if the battery is any good without acid or water? its completely dry. when looking for a new 6 volt battery can I use any 6 volt battery? like a battery of an RV or motorcycle etc..? Im sorry if these questions seem basic but I dont really know electrical|

I'm not that old
IIRC back then batteries were sold without the electrolite (acid). The acid was added just before charging and placing the battery in service.
The condition of these batteries is unknown. The water may have evaporated etc.
They are worth the price of the lead however.
A new battery is the way to go. And keep it charged.

|67Elcamino||Thank you I accomplished what I wanted. To turn the engine over. I havent got it started yet but I need to get me e 6 volt battery. The car came with 2 batteries in the trunk. Both 6 volt but I noticed that they where completely dry inside. if these batteries where laying around for 10-15 years are they gone? can I fill them with distilled water and charge? How can I test them?|

If the 6 volt battery is still connected - in theory it will load down the 12 volt battery and help to regulate the voltage to 6 volt system for a short time.
Be very careful when connecting a 12 volt battery to a 6 volt battery of unknown charge state. A large current will flow to the 6 volt battery resulting in gassing of both batteries. Any spark can ignite these gasses causing an explosion. This is true even when a 12 volt to 12 volt connection is made.

jumped many a 6v w/12v
never had a problem
but most were industrial machines

|EOD Guy||Jumped started many a 6 volt vehicle with a 12v battery.... I turned off anything that turned off, hook up the jumpers and started it...... now I had a buddy next to the battery to undo the jumper cables as soon as it started...... I don't recall ever burning up anything.|

Also, consider the other 6 volt devices in the car like the fuel gauge. 12 volts will fry it. Disconnect it.
Also, disconnect the generator wiring.
The oil pressure and water temp. gauges are mechanical and the ammeter is Ok.
Turn off all other 6 volt equipment.
The wire leading to the coil should have a ballast resister. This will get very hot but helps to limit the current going to the coil. This resister and/or the coil may burn out with 12 volts applied. Possibly replace the coil with a 12 volt but a ballast resister is still required.
Remove the spark plugs and spray some kind of rust penetrating oil stuff into the cylinders. Try to turn over the engine with a wrench before trying to start it in case it is rusted.
Then a pre-lube oil pump should be used to pump oil throughout the engine.
Then spin over the engine with no spark plugs to make sure the engine develops oil pressure.
Fresh gas needs to be flushed through the fuel system. The carb may need to be cleaned.
Check for spark and fuel.
Then put in the spark plugs and_________________________.
