This is a 2004 machine.Sometimes the lights work,sometimes they dont and usuallly the tachometer doesnt work at the same time.
Do you think this could be a loose or defective fuse or some other problem?
Thanks

 

It's probaly either a loose connection or a fuse problem. The fuse holder could be not tight enough on the blades of the fuse or the wire connectors on the fuse holders themself. Sometimes just pulling the connector off and push it back on will fix this kinda thing, same with the fuse holder. They get a little dirty or a bit of corrosion and all they need is the friction of off and on to fix it. Then again it could be the switch.
