When I hook this Sears mutlimeter #82139 up to my car with the key on and the engine off I get a set reading of 30%, instead of 70%. Is it safe to say that it is reading backwards or do I have something hooked up wrong. Btw this is on my 89 300SEL.

Though I haven't used my new one yet nor read the manual in detail, in other posts here it has been said lead reversal is necessary.
