Customer Question
I have an Ariens...

I have an Ariens S14-G that won't start. Usual fixes don't work.

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Good fuel starter fluid doesn't do anything.

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes

Mechanic's Assistant: Anything else we should know to help you best?

I think it might be related to the o31708 relay diode assy.

K321 Kohler engine? Do you have spark at the plug when cranking? Electronic ignition, or the old points and condenser? What is the relay/diode, sounds to be the rectifier for the stator(alternator) and have nothing to do with ignition.

Kohler engine, no spark at the plug, points and condenser.

I've already paid $27.00 now you want $24.oo more?
Technician: Curtis B., Technician replied 4 months ago

The call is an option and not needed. No spark, have you replaced the points and condenser and check the coil?

Customer reply replied 4 months ago
I've replaced the coil, points look good, not easy to get parts for this machine.
Technician: Curtis B., Technician replied 4 months ago

Condenser? If the condenser is bad, you get no spark for the coil.

Customer reply replied 4 months ago
Replaced condenser.
Technician: Curtis B., Technician replied 4 months ago

Have you checked the points with a volt/ohm meter to see if points are grounded when open? Have to be grounded only at closing.

What should point gap be?
Technician: Curtis B., Technician replied 4 months ago

.020 inch on point gap.

Customer reply replied 4 months ago
In taking the points out I dropped the screws and can't fin them. I'm not sure what size they are so I will take a while before I get back to you.

Back again. Points are installed with proper gap also installed new plug with proper gap.
Technician: Curtis B., Technician replied 4 months ago

Spark should fire plug when the points open, do you get any thing ? Do you have battery voltage to the points? Or is there a battery?

Ask Your Own Small Engine Question
Customer reply replied 4 months ago
When I put a voltmeter on the coils plus side of the coil it's low, less than volt.
Technician: Curtis B., Technician replied 4 months ago

With battery ignition, you should have 12 volts to the positive side of the coil. See 8.3 in the service manual link below.

When I connect a wire from the battery to the coil it still does not fire.
Technician: Curtis B., Technician replied 4 months ago

Are the points grounded in the open position? They should NOT be.

Ask Your Own Small Engine Question
Customer reply replied 4 months ago
No, but they aren't grounding when closed either!
Technician: Curtis B., Technician replied 4 months ago

They have to ground when closed!

Ask Your Own Small Engine Question
Customer reply replied 4 months ago
Now it seems to be grounding when points close and not when they are open.
Technician: Curtis B., Technician replied 4 months ago

Points have to open for the condenser to charge, then points close and condenser releases the charge and goes to the coil, where the spark is intensified.

Ask Your Own Small Engine Question
Customer reply replied 4 months ago
My meter says the Condenser is 250-270 nfds. it's connected to the coil on the points side.
Technician: Curtis B., Technician replied 4 months ago

Did you look at the service manual link I sent?

Customer reply replied 4 months ago
item 8.3
Technician: Curtis B., Technician replied 4 months ago

And it is wired just as manual shows? Try the old condenser.

Ask Your Own Small Engine Question
Customer reply replied 4 months ago
I got it to fire and run a bit with some starter fluid. Looks like a fuel problem now. this is with a wire direct from battery. I'm still not sure where the wire from the coil is suppose to get the 12 volts.
Technician: Curtis B., Technician replied 4 months ago

Should be direct from the keyswitch!
