Installing and wiring rear lights/turn signals, 1975 GL1000

Postby chrisbags » Thu Aug 16, 2012 1:18 pm



Hi,

New member, longtime CB750 owner, that bike got totaled thanks to a drunk driver hit and run. I am starting a project on a 75 GL1000 but it has a custom fender, no tail light, brakelight, or turn signals. Sourcing the lights/stalks/wires is no problem, but how do I wire them? My CB750 had a harness with connectors, you just plugged and played, but it was an '01. I take delivery of the bike this weekend so I haven't seen whether or not there are connectors on the master harness - can anyone point me to any resources on this? I also need to put on front turn signals, but I'd like to learn the right way so I can also add a set of running lights/highway lights.

Has anyone else done this? Thanks for humoring a newbie. I hope to collect one from each year from 1975-1980 so if I learn this once I'll probably do it again.

Thanks scott - does anyone know what gauge wire we're talking about here?
thanks!

Seems like 16 gauge wire.

The front blinkers are 1157 style two filament bulbs so they already are running lights. So that same wire would work for your aux running lights. Keep in mind that the stator output is sufficient for stock lights, but not much else. Much power can be saved by using 5 SMD led lights in the gauges and 1 SMD in the gauge indicator lights.

I think you will like that 1975 very much, these are sweet bikes just like the CB750's.

Chris, being new to the GL you may or may not be aware of the electrical problem virtually all four cylinder wings suffer from. The molex type connector under the left side cover near the battery containing the three yellow wires from the machine's alternator to the voltage regulator/rectifier. This connector contains common 1/4" male/female push-on connectors. Unfortunately these connectors tend to get loose and dirty over time. They're a high amperage connection and the failing connection causes a lot of heat which melts the plastic and the wires exacerbating the problem and causing the alternator to fail. I've been through this with both my '79 and my '84. Both times it required a new alternator stator, that requires engine removal. The best way to avoid this problem is to cut the yellow wires on both ends of the connector and solder them firmly, insulating properly afterward. The worst was when new owners added lighting loads Honda never anticipated at the time of manufacture but I've seen this connector fail with only the factory equipped lighting installed. One note: The three yellow wires carry AC and therefore can be connected in any order without consideration to polarity, in other words three yellow wires to three yellow wires not minding which wire connects to which. Perform this simple modification and don't overload the alternator and it should remain healthy for the life of the bike.
