Reverse Problem

Postby edgus347 » Sun Nov 22, 2015 6:27 am



My 97 GL 1500 is a good running bike but the reverse doesn't work right. It switches into reverse OK but it only goes about a couple inches at a time every time I push the starter switch. It doesn't keep on going like my other wings.

Seems I've heard about this before.
Look under the seat for a large dogbone fuse.I think there was a issue with it. Its part of the ground circuit.I don't believe there's volts on it.The fuse box is well hidden behind the crossover mount.
You may search variations of your problem in the search section too.
There is a resistor block and sensor circuit that monitor the motor during reverse that determine the duration and speed of the motor.Be sure all the little wires are attached properly to both solenoids.

When this happens, does the reverse light go out on the dash, requiring you to cycle the reverse lever again to turn it back on?

If so, the bike is detecting what it suspects is a "motor brake" situation, where the bike is going down an incline backward, and the starter/reverse motor could potentially generate more voltage than is being supplied to it.

A potential cause is a bad ground, as mentioned. Other potential causes, from the electrical troubleshooting manual:

No control signal from reverse control unit to reverse relay switch; do self-test A, pin 14.
No control signal from reverse control unit to starter relay regulator; do self-test A, pin 7.

Self-test A involves just measuring voltage on pins on C42 *while it is connected* - between a specific pin and pin 1 (ground). C42 is the connector on the back of the Reverse Control Unit:

Reverse Control Unit
Reverse Control Unit

C42 Pinout
C42 Pinout

Pin 14 Test
Pin 14 Test

Pin 7 Test
Pin 7 Test



Unfortunately, the reverse system, and the controller that operates it, is quite complex, and the tests that are performed in order to determine issues are similarly complex.

The reverse light stays on and it tries to go into reverse but only moves a couple inches and stops, then I hit the starter switch again and it moves another inch.

OK, the first (and cheapest) thing to check is the two 5 amp fuses near the battery. They are under a rubber cover:

In-Line Fuse A and B
In-Line Fuse A and B


Remove both fuses and check them with a meter to make sure they are good. Spray clean with contact cleaner and replace them if they check good.

If they check OK, have a look at the connectors on the reverse resistor array. This requires removing the battery and battery box. Pull the connectors off, make sure they are clean and do not look overheated (both on the wiring harness and on the resistor array). Spray clean with contact cleaner and replace:

Reverse Resistor Array
Reverse Resistor Array


Also, give this a try: Have someone help you, and have them stand in front of the bike. When you press the reverse button, haven them "help" the bike along by pushing the bike backward. The idea is to see whether the reverse system is cutting out because it is thinking it is overloaded.

Edgus347, did the solution that WingAdmin provide a solution for you?

The world is not going to finish today, as it is already tomorrow in Australia and New Zealand, and other islands of foreign nations such as Guam and Samoa.

I've been so busy with all my bikes that I haven't had time to work on it yet but I will after new years. The bike tries but just moves about 6 inches then stops. When I push the starter switch it will go another 6 inches, on and on. I will get to it soon. I have a total of 9 bikes and some have some good electrical problems for now. Thank You.
