Regular theoretical physicist...this guy right here

Hi folks...my name is Brett. I am a new member of the forum and the vstar fam. 1st off...let me say...I love my bike. I did a tune up and came thru that ok. Then I decide to put a Boss mc420 system on...with an illuminated 3 prong rocker switch....and after 2 days Im still trying...lol.
Please help. I've included pics of what I
have done besides burn up 10 bucks in fuses. My finger is pointing at the earth(ground) prong for reference.Any feedback would be appreciated
Thanks!!....Brett

Welcome from Houston, Texas. Blowing fuses are caused by either to much load (amps) or electrical short. Only a meter can answer that. New Members Introduction forum is for us to get to know you. Post your issues in the Vstar forum for best exposure and feedback. Here's a few interesting threads to check out when you get a chance.

Welcome from Atlantic Canada, Brett. I'm afraid I'm not very good at electrical issue but as Les said, if you post it in the appropriate forum I'm sure someone will have some suggestions. BTW, which V Star do you have?

I had to google Boss mc420 to see what you are installing

the listing says its a 600W peak audio driver.

600W at 12 volts is 50A, assuming 100% efficiency.

the listing says it comes with a 5A fuse. 5*12V = 60W max continuous power

this does not add up.

I am not suggesting you use a 50A fuse, if it comes with a 5A fuse and blows it, something is shorted to ground. A bigger fuse will just burn up the wiring.

Welcome from Columbus, OH! As @KCW stated..larger fuse than what the circuit is rated for equals smoke coming out of something if you are shorted....But if you are looking for where your problem is and you are very comfortable replacing wires.. connectors...terminals...switches..etc..I suggest a meter to find your issue...way less painful! good luck!

09 V Star 950

Be seen and be heard! Bright lights and loud pipes!

Enjoy the ride
