Relay Wiring Advice Needed

Postby Captain422 » Tue Apr 17, 2012 5:15 pm



My bike is a 1988 GL1500. The PO modified the cornering lights so that they are now driving lights. They are turned on through a switch on the handlebars. The problem: they are connected to the 12v power source at all times and can be left on when the ignition is turned off ( and yes, I have done this) which can run the battery down.
I would like to install a relay in the circuit. How is the best way to wire the relay using the existing switch on the handlebars to turn them on and off, but only have them come on if the switch is on and the ignition is on?
I know this is a simple procedure for some of you, but please bear with me I am new to this. Thanks for any help you may offer.

You could do this...but it would be much simpler to disconnect the existing wiring from the battery, and connect it instead to the accessory terminal on the fuse block. That will ensure they only turn on when the ignition key is turned on.

Have you checked to see if the previous owner used a fuse when wiring these lights to the battery?

Yes, there is a fuse in the line to the switch. I didn't know if the cornering lights would require more amperage than the accessory terminal should have on it. Yes, that is much simpler and if there is no problem with the extra current in the accessory terminal that is the way I will connect them. By the way Wingman, I ordered the LED's you had posted as replacements from www.superbrightleds.com. I appreciate your reply here, and also the information you posted with the procedures for upgrading the lights to LED's. You guys are are great about answering questions, and I appreciate the time you spend posting photos and describing procedures. It must be a lot of work, but the articles are very helpful to me.

As a point of interest,on the 88, above the horns is a relay attached to the harness. One on each side.they are the original cornering relays.each one has a hot wire on the plug that you can tap onto for your LED lighting.In the plug is a ground and a switched off wire that goes to the turn switch . So if you tie in there,you will see 2 hot wires,operate the turn signal for that side to see which one stays hot.

Thank You to Wingman and virgilmobile. The advice I received from both of you is much appreciated. I have my new LED'S installed on my cornering lights and they look fantastic! Wow what a difference. Thanks to the DIY article written by Wingman I was able to make the conversion to the LED'S very easily. The article Wingman wrote gives a step by step procedure that is easy to follow. If anyone is interested in converting their lights, take a look at Wingman's DIY article viewtopic.php?f=14&t=9444 I think you will be well pleased with the result. Thanks Wingman for posting it, and thanks again virgilmobile for your help also.

Can also power a relay from accessory and break light power through normally open contacts on relay. When switch is turned on it will fire the relay and turn on lights.
