Hello,
I am a little confused. I read how people will test their transom for moisture by doing a conductive test with an ohmmeter.
Well when I measured my transom, I measures some conductivity. in the 200KOhm Range. Because of this I started to do a little digging around. I removed a screw from the top cap and probed with a brazing rod. I was not able to push the rod into the hole any farther then the screw.. Felt very solid.
Then I figured I would do a different test. I connected the ground from a 12v battery charger to one of the transom tie downs. Then I hooked the positive to a lead on my meter. Now I took the other meter lead and probed the other tie down. I got 9V so that tell me that there is a closed circuit. I probed the screw that hold the ladder and also measured 9 volts. This transom conducts a small about of current.
Well I saw a very small pinhole in the sealant by the red arrow. Basically looks like the cut in the fibreglass was a tiny bit off.
I removed that cap, and to my surprise it was pretty dirty under there so I know that water was getting in there.
I poked around with the welding rod into the little gap where the top cap meets the transom and it feels very sold.
Now, I touched the probe of my multimeter to this little gap and I measured 6 volts. I couldn't even see any wood from this gap.. I was only even able to get the meter probe in there like an 1/8 of an inch so I don't even think it came in contact with wood. Intact I read like 3 to 5 volts when touching the probe to on some exposed glass mat and resin.
So then I decided to probe the metal handle in the splash well. I didn't get any voltage reading there so that tells me that there is a break in conductance to that point.
Does anyone know of anything that Champion may have used in their 2000 models that conducts electricity? There has to be something.
Here is an exampe of the two points the I measured..
I am very confused.
