battery light won't turn off, sometimes false headlight/brakelight lights too

[ReSanti]

I've been riding my dad's '82 1100EZ for about a year and I can't seem to get that battery light to stay out. The water lever is good, I promise! The bike starts up like a charm every day. My father suggested that the sensor was too far deep into the "(?) brand" after market battery so we teflon-taped the sensor so it doesn't insert into the battery water so far. That fixed it for a couple of weeks, but then it came back on intermittently. Now it's on all the time again.

I'm curious to learn how that sensor/relay works, any help?

And by the way, I also get intermittent false headlight and taillight sensor lights from time to time.

Any ideas other than trying to troubleshoot the problem by replacing a $80-something OEM lamp outage warning relay?

Thanks!

Ditch the sensor and connect the wire to the + battery post.

Thats the easiest way. Its mounted under the tank just above the carbs.

My battery didn't have a insert for the probe, so I just hooked a wire to the probe and ran it to the positive battery terminal. Make sure you insulate it very well.
Also had problems with those idiot lights sticking, sometimes on, sometimes off, I ended up replacing that relay box under that tank, and also the oil pressure switch. It was intermittant, it supplies the ground for most of those lights when you turn the key on, when the bike fires up and oil starts pumping, it opens the circuit and turns off the lights. In my case, sometimes it would and sometimes it wouldn't.
