So how come you can hand crank a car with a dead battery

Because the 'dead' battery may just have enough juice to power the ignition system. If it is totally flat then you don't stand a chance.

Very old cars and motorbikes had magnetos which generate the electricity for the spark. You can start them without a battery.

In My experience you need at least 8v in there to have any luck. With a DEAD battery reading nothing on a multimeter) even rolling down a steep hill over about 100m won't get you anywhere.

You can make a 2cv run on a 9 volt battery (little rectangle block battery) I once did that on points, will work with my ignition too I'm pretty sure, however don't hit the brakes/lights or its gone....

and you need to take the connection of the dynamo of.... (I guess but I didn't remember doing that.)

Exactly - I rolled down 10 km at an average of 7% in 3rd gear trying to start and there was nothing.

Only a boost from a 12volt booster got me home in stages.

But now I have fixed my dynamo there is no stopping me :)

thanks for that guys, I tried it with a battery but still no joy, probably the plugs, and all the earths need shining up. anyway the blokes pickup has arrived so i´ll have to be working on that for the next month or so..the thing is massive you could get the azu on the back of it!!

guess who´s a happy bunny !!!!


ME ! :D :D :D

arfur is alive.. the new old starter motor arrived today, and after a bit of messing around with cables and dodgy earths it started spinning on the 12 v battery. than after reminding myself of geos advice for starting sidney, I did the same thinng with the cable from the distributor to the coil, and sparks started to happen.

then with help from my daughter and a couple of tubes it started cranking up. now it sucks from the bottle and stays alive really well.

I let it run for a while to warm up and have just changed the oil now also.
no exhaust on it so sounds like a tractor but frankly even then it sounds smooth and solid

vid to follow

happy !
