About

I repair neglected power equipment. This channel was started because I found a lack of good content regarding portable generator repair and wanted to document some of the things I came across to help others dealing with similar issues. These videos are detailed and long, but would rather leave the details in to help those who are learning. Do what I do at your own risk. Generator voltages are lethal. Small engines can cause serious injury. Gasoline is explosive and moving parts can cause serious injury. Always use power equipment outside. This is not an instructional video but meant for entertainment. I am not a trained small engine professional or certified in generator repair. No information contained in this video shall create any expressed or implied warranty or guarantee of any particular result. Any injury, damage, or loss that may result is the sole responsibility of the user. If you want give back, use PayPal: https://www.paypal.com/paypalme/jamescondonYT

Video Description

This is a 20 year old Watchdog branded Generac generator. Recently it started intermittently blowing the system board fuse. The owner did not want to take a chance repair this old machine so instead upgraded to a new one. So now this 500lb generator is ours. Lets run a few tests and see if we can make this machine reliable again. Generator Model: 0053820 Starter used: 0E4271 Start contactor used: 0F3978 Original (correct) starter: 0E9323 Help support the channel by becoming a member: https://www.youtube.com/channel/UCr_GXW2Y56hOpGchXYNqZOQ/join You can also support the channel through YouTube "Super Thanks" or via PayPal: https://www.paypal.com/paypalme/jamescondonYT Visit My Amazon Store: https://www.amazon.com/shop/jamescondon 6 Gauge Ferrules: https://amzn.to/3HDQPnQ 6 Gauge wire lugs: https://amzn.to/3HEbdFp 8 Gauge wire lugs: https://amzn.to/4mQNSiI Amprobe ACDC-52NAV: https://amzn.to/3vRgRy7 Battery Analyzer (TOPDON AB101): https://amzn.to/4mNOQvZ Battery Load Tester (Schumacher BT-100): https://amzn.to/4mmVDNj Db Meter: https://www.amazon.com/dp/B07WHY645V?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_13 Ferrule Crimper: https://amzn.to/4fOWHr1 Grabber Tool: https://amzn.to/45H5YMX Kill A Watt: https://amzn.to/3Ui8WTU Lug Crimper: https://amzn.to/476PU9M Oscilloscope: https://amzn.to/3UkttqL Propane Regulator: https://amzn.to/4mPslH5 Tachometer: https://amzn.to/41Pmcmb I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors. Recently I have been using Simple Green PRO HD with good results. #Generac #Watchdog #GeneratorRepair #Generator #SmallEngineRepair #SmallEngine #DIY #Fixed #Troubleshooting #HowTo
