Flashing OD light, no AC, no Turn signals AHHH

[hammer450r]

I checked every fuse on the truck, #24 fuse is for AC clutch, turn signals but the fuse is fine and there is power to the fuse. Any ideas where to go to next? thanks

How old are your batteries..............

Well i bought the truck a year ago, and he said they were fairly new. Can i check them with a multimeter?

I've been having trouble with the vacuum motor losing power and my AC going to Defrost mode. Now that is working somehow, then all this is what i got in return.

You had better look at new batteries. Diesels are hard on batteries and your problems seem to be all electrical. These trucks show weird electrical problems when the batteries go bad. The volt meter won't show a lot. You NEED to get your batteries LOAD Tested. Most bigger Auto Stores will have a load tester that they can test your truck.

Well the batteries are good, the one needed alittle charge but was good.
I cleaned the terminals and reinstalled and it still is doing the same thing

Of course i didnt get the reading it just said it was good

Now i did pull a fuse while the truck was running right before this happened, dont know if it has anything to do with it.
