Force 40 Choke problem

[eurolarva]

As you turn key to the full clockwise position you are still pushing the switch in? And as you push the key in you loose power to the choke solinoid? Behind the ignition switch is some letters. What color wire is going to the C and what color wire is going to the S? When motor is running will the key shut the motor down when you turn it to the left to the off position?

Re: Force 40 Choke problem

Okay that makes more sense. What is happening is your battery is either low on charge or you have a loose or dirty connection somewhere going from the choke circuit or the starting circuit. Check to make sure all connections are tight and clean and void of any kind of corrosion. If you have to sand all connections till they are clean.

If you have a volt meter set it to DC volts. Charge your battery as you normally would and let it sit for at least 12 hours with nothing hooked up to it including your boat. Check the voltage in the battery. If it does not read above 12.65 volts it is time to get a new one. 12.45 volts means battery is only getting about half charged.

The electronics of the choke solinoid can get kinda complicated. The solinoid is about an ohm. The wire going to the solinoid is about .4 ohms. What is happening is because the voltage in the wire is so similar to the load on the solinoid your battery does not have enough power to provide for both the starter and the solinoid. By firing the starter your battery voltage drops to about 11 volts which in turn because of the wire voltage and the solinoid the solinoid is only getting about 7 volts and needs at least 8 to engage the choke solinoid.

Never mind all that. Get the battery load tested at a auto parts store. Check all battery connections and make sure nothing is loose or dirty.
