Re: Not Enough Power In Car For Stezza
Rymers is that right about relocating batteries?
didnt know that one...I was going to move mine to the boot in the next few weeks.
91_Ea, start with basics,
Check voltage between engine block and battery negative, engine running with headlights, high beams and rear demister on,
Get someone to hold it at around 1500 rpm
If its over .5 volts, run a new earth lead from the block to the battery, and from the battery to the body.
Next, do the same with the + lead from the alternator and + of the battery,
If there is around 0.5v present, run a new wire, with a fusible link from teh alt + terminal direct to the battery + terminal.
Voltage loss in the cables will cause the alternator regulator to "overshoot" trying to keep the voltage constant.
Check the voltage between the alternator + terminal and engine block, then compare this with the voltage across the battery. (do this with the engine running, lights etc on as above) You should have around 13.8 - 14.8 volts at around 1500 rpm.
What cable have you got running to the amp?
This may solve the problem, other than that, try a 1 farad capacitor right near the amp.
[edit: another thing, the power steering pump isnt leaking is it, this can also cause problems with the alternator - learnt that one the hard way, recon alternator went through a set of brushes and destroyed the commutator in around a month]
