Yesterday I received the replacement battery for my sonar. Charged it over night. Put it on the sonar and still NOTHING!? So, it is not the battery that is the problem. I pulled the 3 amp blade fuse and took it an auto supply store for a replacement. They didn't have one, but checked the fuse I had, with their tester and it's just fine.
So, I replaced this blade fuse back in the fuse connecter again, re-connected the new battery and still nothing. I connected the leads to my main TM battery again, just to verify that it would still work with that. But, I got no reading with that either now! I just don't know where to go with this next? I pulled the sonar connector out and reconnected it as well - several times. I still get no start up.
If anyone has any suggestions that I could try, please let me know. Looking more & more like the sonar itself has failed. But I've had sonars for a lot longer with never a problem. Opinions PLEASE!
