Before I installed my stereo and speakers, I keep my battery on trickle charge, and it stayed charged. After the install of my stereo, I put it on trickle charge and it never shows a green light, (full charge). It was a biketronices stereo, so no splicing, there wiring plugs into my wiring. And battery is new. Any opinions on this?

 

Maybe ask Biketronics ...

You could measure the millivolts between the ground wire ad the battery to see if it's in spec with all things off ...

or wait - with no battery tender attached and see if it goes DEAD

but you know that ...

 

Lets see, the radio is using a harness that plugs into the stock harness, correct? If so, all power to the radio and amp (if you have one) should be cut when you turn your ignition off, right? The only thing that should be active all the time is your security system, if you have one......

Let us know the outcome...........

 

check for that parasitic drain....use the multimeter with it off and see what ya get. crazy thing about electronics is that they can be made with mistakes

 

check to make sure your new system does not consume more power than your charging system can deliver. Also, with everything turned off, check the current out of the battery - you may have a drain on the system beyond what the trickle charger can supply.

 

No amp, and no security system. I emailed biketronics, hopefully they can offer a fix.

 

The only thing that should be pulling power in the stereo is the clock with the stereo and/or key off. Maybe the tender light is out or tender bad?
