The light is controlled by a switch. In my shop manual for the 75-79 Goldwing and on my 1976 GL1000, the switch is located on the right side of the crankcase (motor) in the general area of the right hand exhaust pipe.
Brief explanation of the circuit (according to the way it functions on my Honda) is that the bulb has a constant voltage from the fuse block. The ground side of the bulb runs directly to the neutral switch. When the switch is closed (connecting the wire to ground), the circuit is completed and the bulb lights up.
Locate the neutral switch on your Goldwing and disconnect the wire. Make sure the wire terminal does not touch anything on the bike and turn the ignition on. If the light goes off, replace the switch. If the light stays on, the wire itself may be shorting out to the frame or some other metal part on the bike. Inspect the wire for worn insulation along the entire length.
I have 1980 Honda Goldwing Interstate with 55,000 on the odometer. I average 45-48 MPG. Jerry Smith Washington Court House, Ohio
'79 is a 1000 cc , '80 is a 1100 cc. You would have to compare the both. Or check with the parts dealer.
This bike takes about 3.7 quarts.
10w40 will do just fine. I use Motul.
30 to 35 miles per gallon depends on riders habit. some say as high as 45
1980 was the first new version of the Goldwing Interstate. It came with the 1100 engine. That lasted till 1983, then the "84's came out with the 1200, good till 1987, then the 1500's. The 1980 Interstate all dressed cost me just $ 5,000.00 here in Canada, those were the day's.
It lets you only start the car in park or neutral.
The best way would be to pick up a manual. Just too many things to do.
You can use any 10-40 W oil that is intended for motorcycles, made for wet clutch use.
Yes. 10w40 is good. If you don't know how to check the oil leave me a msg. on my board.

They are dark purple. It goes from the ignition switch to the neutral safety switch to the starter.
