Electronics Relocation for open triangle

[Guest]

Looking to relocate the electronics on my gs650e.
A few questions that I'm hoping people can answer.

1. My terminal block assembly(as stated on the parts fiche) is grounded to the frame via the screw, under the white cap is a fuse with one end to a screw terminal and the other end to a 14 GA wire going to the positive terminal on the solenoid. I checked continuity between the fuse and the ground but there was none. What the heck does this thing do? I have a gs550 project bike that hasn't been touched and it also has no complete circuit between positive terminal through fuse and back to ground.

2. Looking to relocate the igniter and r/r to under the tank by the rubber mounting circles. It fits fine but I'm wondering if these areas will get hot or not. The r/r has the big heatsink and is in an open area so it should be good. What about the igniter? Is it temperature sensitive?
I have thought about getting a dyna to get rid of the igniter but I'm spending way too much money on this thing already.

3. Similar to above, the solenoid is to go under the tank just above the carbs. Any issues anyone can foresee heat wise?


The flasher and fuse block will find homes on the seat. Battery is being mounted under the swingarm in a fiberglass box I'm making.

I understand wiring diagrams and such but just not sure about heat sensitivity.

Thanks all!

1.) Without a schematic at hand I would not want to guess. A quick perusal of the schematic should answer your question.
2.) Heat and vibration affects both mechanical and electronic components. The extent depends on how well they were designed and how much of each they see. You can get an idea of what the designers had in mind based on the way and where they are mounted coming from the factory.

There are better places than under the gas tank but there are also worse, mounted direct to the motor is definitely worse.
3.) See 2.) above.

1. Your "terminal block assembly" is the fuse panel. That fuse going to a screw terminal is your AUX circuit. Because it provides power, you should NOT find any continuity to ground. There is another screw terminal right next to the power screw, THAT one should have continuity to ground. I'll bet that if you look carefully, they might even be labeled "+" and "-".

2. The ignitor and R/R both have cooling fins for a reason. They need to run as cool as practical. They are mounted in an area that has moderate warmth (behind the engine) and you want to move them to an area that will be considerably warmer and has virtually no air flow? If you are going to put them there, you will have to extend the wires, of course. Extend the wires a few more inches and at least mount the R/R across the front of the frame just below the steering stem. You might have to relocate the horn(s), but the R/R will enjoy the cooling airflow. The ignitor is also an electronic device and susceptible to heat, but it's not quite as sensitive as the R/R.

3. The solenoid is rather rugged. It will only generate heat while in use, which should be about one second every time you push the starter button. It probably won't care where it's mounted.

Battery is going UNDER the swingarm??? Not much room there, good luck.

Thanks guys - I know my post could have been flamed pretty hard.

Yes it does have + and - labels. The + screw terminal goes nowhere. The - screw terminal leads to the mounting hole. The wiring diagram(non-1982-GS650EZ model schematic attached) shows the the lead from the starter relay to this block but the hot lead goes to the + terminal and stops. The supplemental wiring diagram for the 1982 GS650EZ model at the end of the service manual I have doesn't show this terminal block at all.

I'm not looking to put the RR and igniter under under the tank/directly above the engine. It'd be in front, just behind the steering stem as one of you suggested.
I didn't think of the mechanical vibration being an issue. I'll have to do something similar to the rubber mounts the airbox/electronics are mounted on. If it doesn't work...I was forewarned and have reason to upgrade to a Dyna S and newer RR.

Yes, AGM battery is going under the swingarm. It's only 2.5" or so thick so it fits quite nicely under there.

As mentioned, those "+" and "-" screws are for accessories. If you have a GPS or cell phone charger or something else you want to connect. But, be warned, those terminals are NOT switched, they are HOT all the time, even with the key off, so if you have something connected there, it can run the battery down if the bike is not running.

Ahh. That's what you meant by auxiliary.
I will keep that off then as I don't have a desire to power anything through this terminal.
I should have phrased my statement regarding this block, I was more wondering if I needed this block.
Thanks for the clarification.
