While installing new fuel guage I accidentally created a short (saw a spark close to rear of fuel guage). Now I have no voltage to ignition or instruments. I do have voltage to all other accessories. 2005 210 SSI with 4.3 GL. Checked circuit breaker for ignition, no voltage leading to it. Wiring diagram shows two fuses, 40a for instruments and 7.5a for ignition; can't locate either of these. Any ideas what I should look for?
