I have a generac generator that gets a overspeed alarm after

From https://www.justanswer.com/ythi JustAnswer Customer from San Antonio, TX: I have a generac generator that gets a overspeed alarm after running about 5mins the engine starts fine and runs at a normal speed at first then after about a minute you can hear the rpms get higher and eventually its running very high rpms then it shuts down on overspeed Pearl Wilson: Assistant: Do you know the model of your Generac generator? Pearl Wilson: Assistant: How old is it? JustAnswer Customer from San Antonio, TX: its a older generator think its a 2005 Generac Generator. JustAnswer Customer from San Antonio, TX: Item#(#) #-#Serial#(#) #-# Pearl Wilson: Assistant: How long has this been going on with your Generac generator? Pearl Wilson: Assistant: What have you tried so far? JustAnswer Customer from San Antonio, TX: For about a month I haven't tried anything yet Pearl Wilson: Assistant: Anything else we should know to help you best? JustAnswer Customer from San Antonio, TX: not that I can think of Hank F.: Technician: Hello, my name is * * I am going to assist you with this. Hank F.: Technician: The first thing you need to do is to verify if the unit is actually over speeding or not. Hank F.: Technician: Connect a frequency meter to the output of the genset, and start it up. Hank F.: Technician: Monitor the frequency carefully until it shuts down. Hank F.: Technician: How high does the frequency go before the unit shuts down? JustAnswer Customer from San Antonio, TX: I’m pretty sure it’s over speeding when it’s doing the weekly exercise the generator starts fine and it will ramp up very high rpms sounding like it’s running away with no control. JustAnswer Customer from San Antonio, TX: I do not have a meter that test frequency id have to order one to test frequency. Hank F.: Technician: Is the Over Speed light flashing, or is it on solid? JustAnswer Customer from San Antonio, TX: It’s on solid Hank F.: Technician: Then we are definitely going to have to test the frequency. Hank F.: Technician: You don't have to order a meter Any auto parts store or hardware store will carry a meter that can measure frequency. JustAnswer Customer from San Antonio, TX: Ok I will go get one in the morning and get back with you is that ok? Hank F.: Technician: Absolutely. Hank F.: Technician: Just be aware that I work 2 day jobs and help on Just Answer in the evenings. Hank F.: Technician: Tomorrow I leave for work at 6 and don't get home until about 7:30. Hank F.: Technician: You can post anytime, and I will get the message when I log on. Hank F.: Technician: I may not be able to reply to you right away, but I will reply. JustAnswer Customer from San Antonio, TX: Okay sounds good thanks for letting me know that I appreciate it. Hank F.: Technician: Not a problem. JustAnswer Customer from San Antonio, TX: I checked the frequency when it starts it’s around 60Hz and when it’s reviving up it’s around 70-80hz the battery was dead I had to replace it also it’s the second battery it has killed that will not take a charge. Hank F.: Technician: For it to run for 5 minutes before going to over speed is unheard of. Hank F.: Technician: Your unit has an electronic governor. Hank F.: Technician: The controller gets a speed sense signal from the generator, and adjusts the engine speed accordingly to maintain 60 Hz. Hank F.: Technician: The stepper motor (governor) is driven by a DC voltage. Hank F.: Technician: I have to wonder if the battery charge issue is what is causing that. Hank F.: Technician: Lets go there first. Hank F.: Technician: Underneath your control panel is a bunch of stuff. Hank F.: Technician: Locate the "box" that has 2 wire connectors at it, a 2-pin connector with wires 224b and 225b, and a 3 pin connector with 2 wires 13 and 0. Hank F.: Technician: This is your battery charger. Hank F.: Technician: Leave the genset off. Hank F.: Technician: Unplug the 3-wire connector. Hank F.: Technician: Testing at the pins on the charger itself with a meter, not the wires you removed from the charger, wire 13 is positive, and wire 0 is negative. Hank F.: Technician: You should be reading about 13.4 volts DC. Hank F.: Technician: Now unplug the 2 wire harness, and set the meter to read VAC. Hank F.: Technician: Touch one probe to each of the wires. Hank F.: Technician: You should get about 16VAC. Hank F.: Technician: What do you get? JustAnswer Customer from San Antonio, TX: I tested the 224b and 225b pins on the charger and it was reading 13.8 volts DCI then tested the 2 wire harness and I’m only getting 2vac Hank F.: Technician: No, you need to check for DC voltage at the pins that would correspond to wires 13 and 0. Hank F.: Technician: 16VAC goes in to the charger on wires 224b and 225b, and 13VDC comes out on wires 13 and 0. Hank F.: Technician: Can you please retest?
