I just took delivery of a new Trike with an EIS. It has one warning light located so far out of my line of sight I'm thinking it will be virtually worthless. Has anyone got any ideas, or better yet built something that provides an aural warning through the intercom system? I'm thinking of something more than just a warning horn. 

And, as long as I'm here, the trike is powered by an HKS700E 4 stroke engine that has dual electronic ignitions. According to the manual, and experience in the field, the ignition systems drop off line when input power drops below 10 volts. I'd like to add an emergency backup battery for the ignition system and electric fuel boost pump only. What I'd like is a device that seamlessly cuts in the backup and warns me so I can get down. A Powersonic PS 1270 for a battery looks like a good fit, but doesn't allow enough for a latching relay, too. Is there a circuit that will do what I want with minimal current draw, too? 



Have the moon, wanting the stars, too,

Rick

   How big is your existing battery. How much current does

   the ignition system draw? What kind of alternator and

   regulator is installed?

The aural warning part should be easy as I believe all the GRT EIS units 

have that feature. In fact I believe mine is a 12 volt square wave 

output tone that goes on and off with the warning light. It required 

considerable reducing to feed it into the intercom and is pretty loud 

even with a 470k resistor between it and my intercom input. Even with a 

good light location, it is always the intercom tone that gets my 

immediate attention.

Bob, Good morning. The alternator is a PM type that puts out 210 watts above 4000 RPM. The regulator is a zener diode unit supplied with the engine. The only information I can find on current draw for the ignition is that the CDI's require 3 amp fuses. The battery is an 18ah AGM type. 

I searched the online manuals for any revisions to the ones supplied with the engine and this is all the info I can find.
