Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
When you hooked the new solenoid up did you make sure that the small wire with the inline fuse is attached to the same post on the solenoid as the cable coming down from the battery to the solenoid. If it is not hooked to the same post then the entire electrical system will be dead, you won't be getting voltage to the ignition switch.
I have seen a lot of times when the wiring gets switched and people don't realize it, so I have to check to make sure.
Do you have a volt meter so that we can do some voltage test to determine where the problem is?
Do you have a 12 volt test light?
We first need to determine if we are getting voltage to the ignition switch on the red wire. If you can look at the terminals on the back of the ignition switch you should find lettering on each terminal, we need a constant voltage coming to the 'B' terminal on the ignition switch. If you are getting voltage there then we can check for voltage on the 'S' terminal when you turn the key to start the machine, this will tell us if the ignition switch is working properly or not.
If you can get a meter then we can continue from there. Once you have a meter and are ready to proceed with some test then come back here and we can continue.
All you need to do is come back to our conversation here and we can continue. You should also be receiving email notifications of our conversation here as well so you can also check your email.
Okay, just let me know when you are ready to continue and I will help you walk through the steps to do the testing.
We can continue on with testing once you have the meter to do so.
Okay, first let's test voltage coming to the solenoid.
Set the meter to test VDC.
Touch the red test lead of the meter to the large post of the solenoid that has the cable attached to it that comes from the battery, touch the black lead to a good ground anywhere on the machine and tell me what kind of a reading you have.
Now let's hook your tester to the battery and try to start the machine and see what the voltage reading shows with the key in the start position.
Okay, we need to check voltage coming to the ignition switch. If you can get to the back of the ignition switch, I need to know if you have voltage coming in to the 'B' terminal on the ignition switch, this is normally a red wire that comes into the connector on the switch.
Is that P as indicated or 'B'. I am not familiar with a P terminal on any of these switches.
If that is 'B' then let's move on to another check point. On the side of the starter solenoid there is a spade terminal, can you tell me if you are getting voltage to it when the key is turned to the start position?
If you checked them all and had no voltage anywhere else then the ignition switch is bad and needs to be replaced. You should have voltage on at least two of the other terminals when the ignition is turned on and when turned to the start position.
Based on the information that you have given to me I believe that the switch will solve your problem.
The connector needs to be plugged onto the switch in order to check the voltage that I was looking for. It is easier if you can identify the letter markings on the terminals of the switch so that you can identify where you have voltage if any when you turn the switch.
What you actually want is voltage on the 'B' and the 'S' terminal of the switch when you turn the switch to the start position.
No problem just let me know if I can be of further assistance.
Are you getting voltage to the small spade terminal on the side of the solenoid?
No I didn't because if you are not getting voltage to the 'B' terminal on the key switch or the 'S' terminal on the key switch when the key is turned to the start position it would be useless to test for voltage at that point of the solenoid. I understand that it is not easy to get to these items sometimes depending on the machine but we have to check the system one step at a time. It does sometimes mean going back to other items or locations sometimes in order to check the entire system.
