Automatic choke problem...

Hi,

I hope someone can help me. I have a 1976 610 Datsun with a L 20B Engine (manufactured in Dec. 1975) and the automatic choke is not working. I tested the voltage to it and it is just a little over 2 volts.

Could someone tell me what the voltage should be and if the voltage I read was not correct, could you suggest some possible fixes?

Thank you,

Mike

If you search ebay for a Datsun 610 you will fnd a Haynes repair manual for sale
Good luck

I see it's been a while since you posted, so you may have already fixed the problem. I believe the automatic choke is supposed to have 12 volts. I may be wrong, but I think the way they work is when you turn on the ignition the choke gets 12 volts and keeps 12 volts until you turn off the car. The choke thermostat heats up and opens the choke and keeps it heated (and thus open) as long as you have the ignition on. So an automatic choke is basically a heated, coiled wire that as it heats it unwinds and opens the choke. The reason I'm hedging around is that I am familiar with a Chevy and Mazda choke, which both take 12 volts, so I'm reasonably sure the Datsun would be the same.
