About Eric A. Jones
Expertise
Lawnmower Repair . Certified Master Service Technician from B&S. Have 13 years experience on B&S, Lawn Chief, Weed Eater, Echo, Peerless, Wheel Horse, Snapper, Atlas, MTD, McCulloch, Homelite and many other numerous brands. Specialize in electrical repair.

Experience
Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. I received a scholarship from the Air Force and am currently pursuing another degree.

Small Engines (Lawn Mowers, etc.) - 18 Hp briggs & stratton engine


Expert: Eric A. Jones - 10/20/2004

Question
I have a DR chipper 2002 model 18 HP briggs engine
the charging system overcharges the battery to the point of boiling the acid out of the battery.
Voltage readings using a meter are over 14 volts and climb higher as the engine is run. this has electric start,there is one red wire from the engine case to the battery. does this engine use a regulator? if not what is causing the overcharge? Iput this question to Robert Kapsy
#3738747 could not ask a follow up. This machine does not have much use approx. 50 hrs.

Answer
Are you sure there is only one red wire? Is the end of the wire a round connector?  Not the starter wire.

Please let me know.  I'm very interested in this problem.
Generally the regulator type systems have 2 wires coming from the engine casing and the end of the plug is a retangle shape.  From there the plug connects to the regulator, a square shape metal box.  Then wire(s) run from the regulator to the igntion switch and finaly to the battery for charging.
I'd guess your system is unregulated since you really don't have any other electronic devices to operate like lights or electric clutch.
One more question...does the alternator wire run directly to the battery or through the key ignition switch?

Let me know.
Eric
