wading question

When your battery goes under water why does the solenoid on the pump not shut? i would have thought once the battery was shorted by water the engine would stop.......before i go in anything deeper than the tops of the wheels!!!!.......keith
 
I Would assume that the electricity takes the route with least resistance which would be the wires not the water.. may be making it up mind :P

Well it might, if you were sitting windscreen high in water and just idling at standstill. It won't if the vehicle is moving, the battery box remains mostly dry because the movement creates a void. Basically the same reason why the water doesn't get sucked in to the air intake on the side of the vehicle.
 
so the consensus of opinion is if the battery gets wet there is a good chance the engine will stop? i just want to know what i could or could not do in my 90.........keith
 
Your battery will be safe enough to work under water for a breif period, there is not enough Volts /Amps :rolleyes: produced to bridge the gap between the Poles in sufficient quantity to make any difference.

Now show an HT lead a wet hankie and it throws its toys right out the pram :( , and sulks for a week.

On a similar note...why does my V8 continue to run after disconecting the battery?

Hope its not a daft question :o

I guess cos its drawing volts straight from the alternator. Only when the alternator is creating more juice than needed does it return charge to the battery. I think thats what the rectifier does? If you lose the alternator, then the V8 will run until the battery is flat.

Whereas your diesel will keep running if battery/alternator is removed, only stopping when it runs out of air:D , fuel or the stop solenoid recieves a few volts to activate it (I think)
 
rob i thought it was the other way round, it takes volts to keep the solenoid open, if you pull the lead off the engine stops, hence my original question.......keith
