'05 & '07 Rocket III, '96 Goldwing, '95 Virago
I have two Rockets and I have noticed that the batteries (both new) seem a little on the small size and don't seem to spin the engines very fast or long, compared to my Goldwing & my previous Yamaha XS1100. Their motors are smaller but they have bigger batteries. I plan to order a 12V, 10 second delay relay to wire in series with the headlights to allow a little extra current for the starter motor. I contemplated adding a headlight switch to the handlebar but really don't want extra visible wires. The relay will be under the tank, of course, out of sight and 10 sec should be plenty of time to start the bike before turning the headlights on. What are your thoughts of my plan? Here is the relay that I ordered............ Pardon Our Interruption...
 
The way they work normal is on a 5 terminal so the lights will go out when the starter relay is energised.
a lot of the early rocket guys have installed two relays for the lights and wired from battery so as to take the load out of ignition switch because there has been a lot go bad
i fixed mine a long time ago an the ign switch still works great.
they also have a system that is called the eastern beaver that you can install.
your bikes may have a system already installed.

I don't believe my '05 & '07 have a system as you described, but will check a little closer. I have also never heard of the eastern beaver system but will see what I cam find on that as well. I'm a retired electronics tech and have some abilities along those lines. I much appreciate the info.. Thanks!
 
it has been a long time since i heard of someone buying an eastern beaver
i can help if you want to do relays
