reset?

[webby]

well the battery ran completly out of juice on the hybrid while its sat on my drive for 3 weeks waiting for a chip and now i have charged thebattery it wnt even crank, all it must be is a reset needed of some kind as fuel primes ecu buzzes etc.... whats the crack? sheers, will

[MAXIBOY]

first off why did it run flat in just three weeks without some kind of fault..

then when you charged the battery have you tested the voltage..

and again when under cranking load..

fuel pump requires loads less power to run than to crank the car..

i would think the battery's not up too the job..

i had an amp lead shorting the battery i think and it ran down quite quick shall leave it on charge alot longer and see the case tomorrow

[MAXIBOY]

they are not designed to run fully flat really car batterys might have killed it..

np, new battery can be sorted tomoz if its not charging. ty

i have fitted a new battery and still the dash lights come on (battery handbreak etc) and the oil guages flick up but nothin happens off the key? next to my engine temp guage a red bulb is lit, not sure if thats normal... any wizards out there that can help pwease?

immboliser fault maybe..

or second thoughts i'm sure they still crank..

so either a bad earth
the starter motor solenoid wire has come off or failed completely

Its not uncommon for a battery to be run flat within a couple weeks, even a week if its sat doing nothing. It all depends on the condition of the battery and how many times its been "run flat", and its remaining capacity/ability to be charged fully.

A car battery is not a truely rechargable battery. If you run it flat once, it will only ever recharge to about half the original capacity, do this a few more times and you have a car battery with very little capacity, even though it may start the car (starting a car requires only a little power, as little as 1amp/hour), so the juice can go right down until all off a sudden it wont start/power anything.

In these circumstances (battery not ever fully charging properly) people often believe the alternator to be at fault - which is normally very unlikely.

Basically if you let it run flat your ruining the battery.

does the car still crank?

if so may be a dodgy ecu chip (gunnerchip right?), try your original chip and see if it works... if it turns out to be your gunnerchip i can do you one.
