Today I worked on my car with a friend. I’ve been chasing a flakey ground on my car since it came new from the shop back in 2004. Basically my alternator light comes on very dim when not using the headlights. As soon as I start using them the alternator light goes nuts turning on occasionally. We did see two grounds for the negative battery cable: one to the top of the steering box to one of the 13 mm bolts on the top cover the other one runs to a metal bracket over the front beam right in front of the gas tank which attaches to the fiberglass in that area with two 13 mm bolts; the ground goes to the left bolt. We cleaned both and now the problem seems to be resolved. Will report as time goes on to make sure we really solved it.
Now on to the main subject of the post. As soon as we finished that it started pouring rain. I put the top and the side curtains up and waited. It rained cats and dogs for over an hour. Normally if the car is still it doesn’t get wet inside so I decided to wait until the rain was over for a while to drive back to store the car. When it subsided and I went to start the car it started cranking and wouldn’t start. Then all of a sudden I heard like a loud knock on the motor and the starter couldn’t crank it. The starter suddenly stopped responding and all we could see when turning the key was both oil and gen lights light up and go dim as if the battery were dead. That’s when I panicked; that noise didn’t sound good and I thought I’d broken something major. Also the battery is brand new. We waited a little and then the car started but was spitting and I revved it a little and saw some white smoke. I turned it off and opened the decklid and found the engine compartment fairly wet with water at the top of the air filters on the carbs and all around the bottom of the filter elements. We decided to open the air filters and take the elements out; I found some water at the air filter bases which we dried up. We installed them right back up; started the car and at first it was missing a little bit; I revved it a few times and it came back to normal. The car worked perfectly on the ride back. I am thinking it might have hydro locked a little. I am surprised the engine wasn’t destroyed. Looks like these decklids will let in a lot of water under a heavy downpour. Be careful. What are the thoughts of the brain trust here? Have any of you experienced something similar?
