DR2A stands for Drive 2 Gas
DR2E stands for Drive 2 Electric

For simplicity, you can get an inductive hour meter that has its own internal battery and connects to the spark plug wire. It only counts engine running time.

Here is one with maintenance reminders and has its own replaceable battery: Inductive Hour Meter

No backlight but who's reading an hour meter in the dark?

Thanks everyone. I appreciate the information and have some follow up & questions.

I knew the time meter would not be the true engine running time but feel it is not that important for me. I only stop when changing between forward/reverse, with traffic/stop signs, and when parked. So far, traffic has not been an issue for me. I am not yet a golfer but expect I’ll just turn off the key when stopping during golf. Anyway your information is good to know, others reading this may not be aware of that.

Is the red/white wire which indicates the engine running only available in the engine compartment or is it available behind the dash board?

The meter I’m using does not have a battery. It uses non-volatile memory.

The switch at the gas pedal is in the floor. Doubt the wire routes up behind the dash.

I believe A=gas, a different letter I can’t remember which, means electric.

It’s very simple, the cart only takes one quart of oil so take all the guesswork out of the equation and just use the best. That would be a quart of Amsoil small engine oil. Costs about $12. Don’t worry about mileage or hours of use, change the oil once per year, and completely drain out the old oil, don’t pump it out. Easy peasy.

If it is running fine and you do routine maintenance on the Yamaha’s, it will outlive you if you keep them that long. You will have more maintenance on other things than you will the engine.
