my ranger only has 4,000 miles on it and it has seen the tow truck 4 times already. the inertia switch keeps brakeing not tripping. i dont have my license so the truck has never been off-roaded with. if it happens one more time my dad is gona file it as a lemin law and get a new one. has anyone elts have or had this problem?

 

have they replaced it? ... the dealer could just be replacing it and not finding the actually problem, a short to it somehow ...

mine shorted out on me once ... had to rig it up so i could get to work to replace it....

ya they repaced it 3 times already and it just happend again backing out of the driveway.

 

i didn't even know there was an interia switch, where is it located?
It sounds like either you have a really bad bump at the driveway, or there is a short.

 

pass side footwell

at the top of the carpet in the corner

you can trip it with a key once you know where to look (really freaks the driver out when the truck dies)

 

Can someone elaberate on the "inertia switch" ive heard of them but dont really know what they are for...

Thanks

It senses impact, assumes you've been in an accident, and shuts off the fuel pump.

 

there must be an intermintent short somewhere and when you hit a good enough bump it shorts out.... tell the dealer to fix it besides throwing a part at it .... first time it happened ok could have been a bad part .... 2nd or 3rd time they should have dug deeper into the problem....

 

Not neccessarily. If the switch is normally closed, then a short isn't going to effect anything. Not every electrical gremlin is a short circuit.

 

if its a closed circuit all the time ... a short would effect it .... now if it was an open circuit all the time then ya a short wouldnt effect it....

couldnt it be the fuel pump is drawing to much amperage?

im just trying to ask questions not saying yo uare wrng or right just tryin to learn

 

Not neccessarily. It depends on what it is short circuiting to.

 

im gonan IM you lol
