Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
Yes there is a charging system on the engine that should keep your battery charged when running. Do you have a volt meter? We can run through a couple of test to help identify what the problem is.
Can you locate the voltage regulator on the side of the engine? It should have three wires going to it, two will be in a connector together the other one is by itself.
We will start by making sure that the wires are connected onto the voltage regulator properly.
If you look at the voltage regulator two of the connectors are tied together, the two wires in the connector together will go on these two terminals.
The regulator has one single terminal which the other single wire should be attached to.
If the wiring is not hooked up this way the charging system will not work properly.
If the wires are connected properly then we will continue to test voltage.
With the engine running at full throttle, set you volt meter to VAC and touch one test lead to each of the two terminals with the two wire connector attached to them, you should see at least 28 volts AC on these two wires. If not your alternator is bad and will need to be replaced before you can go any further.
With the engine running at full throttle, set your volt meter to VDC and touch the black test lead to the single terminal and the red test lead to the positive post of the battery, you should see something between 14 - 15 volts DC. If not you voltage regulator is bad and will need to be replaced.
This was most likely the problem. I see it often when people unhook the wires they don't realize that there is a difference. If you hook it up the right way your problem will most likely go away. However it could have damaged the alternator and/or the regulator by being hooked up wrong. It will still be a good idea to at least check the two just to make sure that everything is okay.
Let me know if you need additional assistance.
Great!!!! Hopefully you won't have problems again for a while.
