Howie, it was a joke bro. I was saying how some people will do that. For example: my clutch release 12v wire is black, the - is red. I was being sarcastic. I got out a dmm and checked the polarity and load.

Well after a day of monitoring the battery it is at a steady 12.35 volts. Looks like the relay was bad. Thanks guys!

12.35 seems low, is that across the battery terminals?

Also how old is the battery?

I just realised that previously you said you heard the relay click.

Well unless it was internally shorting across 87 and 30 there's therefore nothing wrong with the relay.

A fully charged battery with no load should read 12.65V.

Ditto.

12.35V is 20% - 30% discharged, and 20% is the usual limit for a cranking battery (50% for deep cycle).
