New Battery

LMAO!!!!!!!!!!!!

Thevenin - Replacing a complex network with a single ideal constant voltage source with an internal resistance in series.

Norton - Replacing a complex network with a single ideal constant current source with an internal resistance in parallel.

Thevenin Voltage (Vth) - The open circuit voltage (i.e. the voltage under no load) across the terminals of the network in question.

Norton Current (Inort) - The short circuit current (i.e. the current flowing under a short) flowing through the terminals (and through the short, of course!) of the network in question.

The Thevenin Resistance (Rth) [also Norton Resistance (Rn)] - The ratio of Vth/Inort

Rth [Rnort too!] can be also calculated/checked by replacing all the voltage sources with short circuits, all current sources with open circuits, and then calculating what the resistance 'seen' by the network terminals is.

Geez, that takes me back! :p
 
I used to live next door to a bloke with a tatty Rolls Royce he used for weddings . He would take the battery off his Mum's Triumph Acclaim to start the Rolls .
 
I've got an optima redtop battery on my P6, seems to do the job ok, and fits into the battery box, I had it on my Mitsi diesel pickup truck. The beauty of these is that they don't get knackered by sulphating of the plates if not used for a while, and are gel filled, and can be used any way up. I got mine from These guys. It wasn't cheap, but this was the cheapest place I could find these. They deliver for free too. It certainly whips the old lump over quickly enough.. (815amps cold cranking current)
