Thanks, I found that with the MX5 too. Luckily we have a good Auto electric guy here even if he isn't a rotary guy. I'll PM you when I get a chance to come down. I was hoping this weekend but its gone **** up
Soon though, I'd like to get the car looked over by someone that knows about them.

This is the opposite of voltage.

Hope that helps.
Until you get a short, and then go BOOM!

In which case grab a beer and enjoy the show.

lol well yea, but that's why any and every demanding circuit has a fuse. (well ... if you are smart and care lol)

And yea ... i remember one day way back when in circuits class ... teacher told us to be careful when working on cars not to accidentally place a wrench across the battery ... and if you do .. run lol.

my 09 needs a new battery. it still cranks but just slow. also if I don't use a battery tender it drains slowly.
called dealer said $99 bucks for a Mazda battery. I wonder if its the same battery.

If you are a Costco member the Kirkland warranty can't be beat; free replacement or refund for the first 36 months, then pro-rated out to 100 months ... Great price too, won't use anything else in my street vehicles

My Costco Group 35 Interstate battery has the same stampings and markings for date/factory/lot codes as the Mazda 36/60 battery it replaced. Even the handle is exactly the same. $73 out the door at Costco this week (not on sale).
