I searched but to no avail, I couldn’t find anything on what I am looking for.
Thank you in advance for your help.
I am riding a 2007 mp3.
I thought my battery had died so I changed to a new one. Still no response. She dash lights up but dimly. No other lights other than the head lights turn on.

I am thinking it is a a relay. But I am not sure. Does anyone have any advice or knowledge on the subject.

Can you get a multimeter and measure the battery voltage?

Under 10 volts, lights will come on dim but ECU needs more than 10 volts to work. So I am guess another bad battery, as you didn't say you got a new battery you said you got another battery. MP3 is Very sensitive to proper battery voltage.

Thank you one and all. Got her running. Ended up it was a fuse. Happened to not be connecting.
