Sounds like your on the right track, I would just take the reverse apart and see what you find, but make sure to check cables and such first. It is posibble the starter could cause the problem, but I would put an amp clamp meter on the reverse and see if it's putting out like the forward. Good Luck. Keith

Pull the cables and clean the connections. The Yamaha solenoids need a very good connection to work properly. Just keep track of where all the wires go when you remove them to clean the terminals.

You may be surprised and delighted after cleaning the cables. It may works just fine including the reverse beeper.

Here you go -- terminal cleaning 101:

Use standard safety precautions. Battery acid can burn your skin and / or blind you. This means safety glasses should be worn. Latex or nitrile gloves are a good idea as well.

DISCONNECT AND CLEAN THE BATTERY
1. Disconnect the positive and negative cables from the battery.
2. Clean with a standard battery post cleaning wire brush or equivalent you can buy at a local auto parts store. Use battery post cleaner (auto supply spray) or a simple solution of baking soda and water to neutralize any acidic corrosion in and around the posts and the cables.
3. Rinse with water and leave disconnected until the solenoids are cleaned.
4. Dry with a rag or compressed air.

CLEANING THE SOLENOIDS
1. Either take a color picture of the solenoids so you can get the wires back in the same location or mark each wire and draw up a sketch that describes where each wire goes.

2. Clean one solenoid at a time using a wire brush or scotchbrite pad. You want the copper to glisten in the light after cleaning. I use a 3M Scotchbrite abrasive pad on a 90 degree air grinder to clean things up. You may have to do yours the old fashioned way.

3. Reconnect all the wires and cables in the same location.

4. Clean the other solenoid and reconnect all the wires and terminals.

5. Reconnect battery posts

6. Attempt to start the golf cart in forward and reverse key position.

7. Post your results and let us know how it worked out.

If you don't feel comfortable doing this type of routine maintenance then consider the post powerful tool in your DIY toolbox -- your checkbook. You can write a check to the local golf cart service center to fix the problem.

Thanks. I just used it myself on my golf cart. I didn't have the time or information to rebuild the motor in my G1 so I broke out ye old checkbook and paid my local Yamaha service center to install a rebuilt motor. It was great. While I was at work the service tech comes to my house and R & R's the motor in less than 2 hours. Best of all it runs great.

Now I am installing Club Car roof on my G1 using the steel cargo box that's bolted through to the frame. The back vertical support is done. Next is the cantilevered portion of the design. I think I will use 1/8' wall 1" square aluminum tube for this support piece because the shear load is greater. I have $50 in the roof and probably another $20 in aluminum.
