Electronic sanitation and preventive maintenance

[agrady1995]

I am in the process of changing my alternator. I bought an aftermarket USA made high amp output alt, and on my IS, had to remove the battery box to get to the plug for the cable... I am going to go through and clean the wires inside. at 96k and with a love of Florida's WMA's, Me and my wife have some DIRTY interiors.


I am wondering, based on the image here: https://www.partzilla.com/catalog/honda/motorcycle/1999/gl1500cf-ac-valkyrie-interstate/wire-harness

Which Relay is responsible for the headlights? I have had (since I bought bike at 49k) an intermittent problem with the headlights cutting off and not coming on until multiple power on/off cycles. I am hoping to change it out. If you could describe (from reference of the picture) the relay location and callout #, I would greatly appreciate it. Perhaps another way to identify it?


 Any suggestions for cleaning the dirt/dust off of the harness, and or plugs?

I found it on page 36 of the Honda Service manual. You did mention IS.

Don't have the manual? Valkyrie Norway

Spent some time with my electrical system today, cleaning and inspecting wires. Not as bad as I thought it was initially. I think that's the last section of the bike I haven't torn apart...

My alternator puts out 80A at 300RPM, which is Double stock. Should I get a 100A fusable link? I know the stock one is 55A so I would like to be sure I don't blow it up...

The factory used a 55 amp fuse with the gauge of the wires etc in mind. If you set 100 amps to blow the fuse, it might damage the electrical system even the ICM instead of the sacrificial fuse. Is the new alternator's 80 amps near or at peak current? True, I have no idea whether you'd have to replace a 55 amp fuse too frequently.

Is the 55 amp fuse just for the alternator current?

Keep the main fuse at 55A.

Run all your aftermarket accessory electronics through a PC-8, Fuze Block or similar fused distribution panel whose master relay is armed via the main harness Acc connection. Don't run accessories (other than the Hondaline CB rig) through the main harness itself, and keep the total load of both main harness and additional devices to under the rated output of the new alternator (80A).
