It is not repeatable, I can't do something and know it will happen. It just does it's crazy motions almost none stop.
I know it has to be an electrical issue but I don't know where to begin.
Can someone tell me where to begin. I have a fix'd fob that I can connect and get the engine codes. I have looked at them but they are not specific enough to find the issue.
First off; Posting the specific DTC codes you are receiving would be a good start
, for anybody that's trying to help you;
I always refer anybody who is having electrical problems here;
This is an excellent thread about the Junction Block with detailed information, pictures and diagrams. The Junction block is the assembly located under the dash just to the left of the steering wheel. It contains 30 fuses and has many of the electrical circuits used in the Commander. There is also a PDF document attached to the thread above, that explains in detail how to remove your Junction Block, in the event that you need to replace it.
Since you've had water leaks in the past, I think a thorough inspection of your junction block, the associated wiring going to and coming from it, as well as all of the fuses contained within it, is in order.
I would also get your battery checked again, make sure it's still good. If your battery checks out good and your junction block, associated wiring & fuses look good, the next thing I'd start looking at is your alternator.
There is also a yellow wire that connects to your starter. When this yellow wire connection to your starter gets corrosion on it, it's been known to cause a lot of electrical problems. Check the connection where that yellow wire connects to your starter - if there is any corrosion present on that connection, disconnect your battery and clean that connection with a wire brush until it is completely clean and free of corrosion; Then reconnect your battery and see if there are any changes.
