If motor doesn't turn, either the Forward/Reverse Switch or the Starter/Generator needs testing. If motor turns, the solenoid is defective. If voltage is PRESENT, jumper the two LARGE terminals on the solenoid. With the ignition switch ON and the gas pedal DEPRESSED, check for 12 VOLTS at the small terminal of the solenoid that is not GROUNDED. If the starter/generator fails to turn over when the gas pedal is pushed, perform the following tests. A slight gap is normal.ġ2 volts is supplied from the BATTERY which flows through the CIRCUIT BREAKER, IGNITION SWITCH, MICRO SWITCH, through the SOLENOID then to the FORWARD/REVERSE SWITCH and STARTER/GENERATOR. The pedals should not be missing or bent. Rebuild the carb with a rebuild kit and flush all the passages out. It is important that the crankcase is sealed and the compression is good. Good spark but no gas entering cylinder? The FUEL DIAPHRAGM (located in carb - '63 to '81) works from the engine vacuum. Line this mark up with the punch mark on the side of the housing. With the points cover removed, you will see a scribe line on the points plate. IT IS IMPORTANT TO NOTE THAT AUTOMOTIVE PARTS WILL NOT WORK PROPERLY AND CAN CAUSE DAMAGE, NAMELY POINTS (the points spring tension, if too much, can wear down the cam lobe and if not enough, will cause the points to bounce). BAD REED PLATE would be suspect if there is a back flush of gas in the air cleaner Crankcase ok? Check for spark NO SPARK or WEAK SPARK.Make sure points and plug are gaped correctly (see ENGINE category) If there is a sign of arcing OR a lot of spark at the POINTS, replace the condenser. BAD OIL SEALS would be evident by an accumulation of dirt either behind the stationary flange (the flange on the crankshaft) or around the fan shroud. If the compression is fine, check for a sealed crankcase The crankcase is sealed by the CRANKCASE GASKET, the OIL SEALS and the REED PLATE: BAD GASKET would be indicated by accumulation of dirt between the crankcase halves. Remove the carbon from the piston top to get its size.
If the compression is low, in either direction, a broken ring(s) is the problem. If the compression is high, disconnect the muffler to see if the compression returns to normal. A higher compression, 10-15 psi over, would suggest either a blocked exhaust port, build-up of carbon on the cylinder head or a BLOCKED MUFFLER. The first task to do is a compression check The compression should be approximately 80 psi in FORWARD and 85 psi in REVERSE.

1-1/2 ounces of 2 cycle oil to 1 gallon of low octane gas (85 to 1) is the correct ratio. A high quality, certified 2 cycle GOLF CART OIL (TCW-3) is mixed with low octane gas. The engine is cooled by air and displaces 245cc. Harley Davidson used a 2 cycle, loop-scavenged single cylinder engine with a reed valve intake. The last number indicates the year of the decade. MANUFACTURE & YEAR The letter H (made in the '70s) or J (made in the '80s) indicates the cart was manufactured by Harley Davidson The letter C (made in the '80s) or D (made in the '90s) designates Columbia as the manufacture. 1982 was the LAST year that Harley Davidson produced a golf cart. If your cart was made in the '60s, the first two numbers designate the year and the next letter(s) designate the model as in this example: 64DC800025 This VIN would indicate that the cart was made in '64 and is a model DC If your cart was made in the '70s or '80s, it will follow this format: 3B12234 H4 This VIN indicates it was made by Harley Davidson in '74 (H4) and is a model D (3B). It's important to know the correct year so you can get the correct Harley Davidson parts This number is located on a metal plate that is affixed to the frame directly above the driver's rear wheel. To find out the year of Harley Davidson golf carts, you will need to know the VIN.
