Alternator Idiot Light

Post by Terry D »



I am wondering if anyone knows how to hook up an idiot light that warns the rider if and when the alternator is going or gone south. I have a 2005 GW with a volt gage. But it's location is not great to notice immediately if the alternator is no longer charging the battery. I was thinking a good location for the light would be on the dash, maybe near a speaker or towards the center. I know Tom Finch carries a spare alternator and tools to replace it on the go. I had to replace the brushes on my 92 1500 alt. once at the 55,000 mile mark and replaced the entire alternator, again at the 112,000 mile mark. But, Never on either this current bike or my 2001 GW.

If you want one that you can mount anywhere this might be for you

The best one I think is analog. You can see it anytime of the day

I have not seen an "Idiot Light" for a wing yet. You will need to go with a digital gauge like Joe is showing. I have the digital one from Electrical Connection. It is plug and play and is mounted behind the left speaker grill. It is always visible at a quick glance.

It is showing that it is for a 2006 and up. You would have to call and see if it would work on your 2005. If not, you at least have an idea of what it looks like so you can use the one that Joe is showing.

I have something very similar to the tri-color LED shown here on my bike:

I think I found the easiest and best solution to add a battery warning light. At American Autowire they have an 11 Volt Sensor, Part Number 510287. This sensor is hooked to a switched battery supply and then to a chassis ground. I figure that I can make a connector for this to happen by adding it to the volt meter in my right side panel or buy the Y pigtail where the voltmeter is plugged into. Then run the sensor's red wire up behind the right side speaker along with the black/white wire to power either a incandescent bulb or an LED. It is important for the Red to be positive on the LED but not so important on the incandescent bulb. Cost is $34 for the Part plus the socket and bulb of choice which I already have. The light comes on when battery voltage is 11 volts or less and stays off if Alternator is keeping the battery above that. This allows the indicator be within sight while watching the road. The voltmeter can indicate the same thing but you have to look down to see it and recognize immediately where the gage needle is pointing. I really like the option this sensor provides

My vote is ditch the gauge and forget the light for one of these from Electrical connection. less wiring and its right there.
