First off, I am not very good with car electrics. !
The vehicle is a Suzuki Vitara but I am guessing faulting is very similar across vehicles.
Last used the car on Saturday. It was fine. Went to use it last night and turned the ignition key and no lights on the dashboard. No dull click or anything with starter.
The car has what I thought a few months ago was a primitive code panel that operated just the fuel pump. It actually is an immobiliser as well. It lights up but even when the code(666?) is input the red light stays on even though the green is now on. In the past the ignition lights come on regardless of whether you have input the code and you can crank the engine but without the code doesn't start.
Interior light works but very feebly.
I have had the battery on charge overnight with no success. It went to rapid charge and this morning settled down to normal charging suggesting the battery is taking charge. Still no dash lights. However having tried ignition key the battery charger went to standby mode. Battery terminals look tight enough.
I do have :
1. A digital multimeter DT-830B (but don't know how to use it!) I set it to 20 DCV and it showed -1 on scale before and during prodding the battery terminals
2. A spare battery with some charge . Perhaps the battery has got a collapsed cell. I'll try jump leads across to my spare battery now.
3. Home breakdown recovery. That will pose me huge logistical problems though if/when I have our only car taken away.
Thanks in anticipation
