Does anyone have the specs of what a westco type battery should be reading?
Im still having concerns with mine its about 3 years old and has been charged with an optimate 4 charger , lately its been stored in a lockup with no power and only seams to last a week or so then wont start, battery terminals are good clean and tight all earths are clean including new engine earth, no alarm is fitted just an MX5 parts clock and cubby hole . nothing else is permanently live.
Readings Im getting today are :
battery voltage 12.74v at standstill, when engine running 14.3v so I take it the alternator is charging ok ?
car is used weekly but often very slow to start today I rolled it back and bumped it out of the garage . When the car has been used lately it has been on road rallies at night so lights on, maplights on but not stopping the engine for a couple of hours etc
Could it be the clock? if I disconnect the live feed and put a multimeter in line to it what sort of amperage should I see if its ok? would a digital clock use less amps than my manual one if so any suggestions for what fits (does the Mk2 have a digital clock?) I would want it to be lit up at night for rally use ?
Also (and it might be a clue ) the clock backlight has blown and appears to be all in one with the wires (not a removeable bulb ) any idea where I might get a replacement , Ive tried MX5 parts and they are looking into it ?
Finally has anyone fitted a cut off on the battery and would this help if so was it simple and where did you put it ? I was thinking of putting it behind the drivers seat but it could go in the boot?
