Yamaha Grizzly 550

Today's project was a Yamaha Grizzly 550 ATV that would not start.  This is a newer machine with a fuel injected engine.  When I turned the machine on it displayed an error code "33" on the instrument panel.  I looked in the service manual and saw that code 33 was for an ignition fault.

I had to remove a body panel to get at the ignition coil, and once I saw it the problem was obvious.  One of the electrical connections to the coil had corroded so bad that it fell off.  Most repair shops would probably tell the customer that they needed to buy a new coil (probably $75), but I decided to try and save this one.  

I used my Dremel tool to grind away the plastic case on the coil and exposed a non corroded portion of the connection inside.  I then soldered a wire to this spot and crimped a new tab on the end of it.  To finish it up I put the coil back on the vehicle and sealed all the connections with "Liquid Electric Tape".

The whole job took about an hour and I avoided the cost and wait of ordering a new part.
