SOURCE: trying to power a amp with 16 volts. possible?
Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??
MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.
The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.
More input voltage means the amplifier will have to work less hard to make power.
Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.

The first thing I would do is lift the seat and check the battery connections. Those batteries are notorious for corrosion at the terminals. Make sure every connection is clean and solid, as in no loose, corroded or frayed battery cables. Next, if the batteries check out, toggle the run/tow switch, also under the seat to make sure it is fully engaged into the run position, and finally check the forward/reverse lever to make sure the connections are clean and tight.

so many possibilities...
does it roll fairly freely? (checking to see if the brakes or rearend seized up)
Are there any "bad" sounds like things grinding? (Connection between Motor and rearend, axle splines...)
If all that is solid, it is likely in the controller.... (it takes a solid charge right... No bad batteries in there or loose connection? might want to check all the battery connections to make sure none are burnt...)
1997.. does it have the electonic speed control by that year? the other possibilty is that the accelerator is not working corectly. they used a resistor system on old ones that has contactors that would get worn out.... Newer ones control a potentiometer(sp) that controlled the speed.
Only a few real components to check, but if you are not mechanically and electically inclined, could be tough to isolate.
peace,
