0.9V lost in the cable, _while cranking_, is something near a 10% loss! Sounds unacceptable to me.
If this is just while sitting, something else is drastically wrong. Have you tried using your jumper cables to tie battery + to the big terminal on the starter? Bypass what should be perfect heavy cabling, using temporary heavy cabling. Any difference then? People tend to think of wires as perfect. They are not, they ALL are resistors. Just, we hope, very small ones. Measuring the voltage across a wire under load will show the imperfection. It should not be much. What 'ground' cable between the solenoid and the starter? The schematic of the heavy-current starter circuit is dirt-simple: +------------+ | | ------- Bat- ====== Star- --- tery ====== ter | | +------------+ Ideally you are measuring the voltage between the two '+' symbols on the top, and also between the two '+' symbols on the bottom. Neither should show any significant voltage while starting. If the wires were perfect, they would read zero. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
