Because it doesn’t have a variable voltage alternator lol.

All the ones I have are quite variable! Until they stop altogether!

Dropped into Jaycar and bought a new multimeter, battery sitting on 12.71V after being on the charger all day yesterday then sitting overnight unplugged out of the car. Will do a load test tomorrow and see where we stand, don't want to replace the battery if its still good.

Did some testing this morning, with headlights on voltage dropped to 11.91, when cranking it dropped to 9.96.
So i think i can safely say its fooked, will pickup a new supercharge MF88H on Monday morning - found one for $209.

Did some more googling and read fault codes again, P0191-24 came up being fuel rail pressure sensor failure. Went out and checked and sure enough i must have knocked the sensor when i put the engine cover back on after an oil/filter change last weekend .

I was in Supercheap today and see they had a century battery that is the same as the supercharger , think its a Din88LH ? or something like that , and it had 930 CCA , the other Din88H was 730CCA , both were around the $250 mark..... just an option if you want a few more CCA

I just had occasion to check. The MF88H was $223.30 in April. 900CCA / 160RC.

If I had the option I'd trade CCA for RC. Don't need anywhere near the cranking amps, but the capacity is useful.

Fitted the new battery Saturday morning, boy it sure spins it over now!! What a difference, oh and no special programs or transmissions errors on the dash now

SSB SS88TI
1180 CCA
250 RC
92a/h

Will see how long it lasts.

cheers
