sounds liek it could be working ok, but i would expect it to go back up into the plus+ when the engines running and the lights etc are on.....

 

it also shouldnt drop into the minus- when the ignition is frist switched on, unless youve got fuel pumps and the like coming on with the ignition?

Yes, its wired the right way round, it will go into the neg when you load it, it tells you what the battery is taking to charge, TBH it dosent really matter if its round the other way, it will still tell you exactly the same, but the needle will sweep in the other direction,
