Bigj66 264 Posted January 6 Share Posted January 6 Can anyone recommend a generic inertia switch that I can retrofit to my V8 conversion to shut down the fuel pump in the event of a shunt? One that can be manually reset rather than linked to other vehicle systems. Are they normally mounted on the bulkhead? Quote Link to post Share on other sites
RedLineMike 129 Posted January 6 Share Posted January 6 from your discription id suggest a td5 one, its 2 wires with a push to reset Quote Link to post Share on other sites

RedLineMike 129 Posted January 6 Share Posted January 6 on my td5 i replaced the inertia switch with an emergency stop button mounted on the dash Quote Link to post Share on other sites

Mo Murphy 717 Posted January 6 Share Posted January 6 I have one in my 200tdi, it cuts off the stop solenoid and the electric fuel pump. I used a s/h TD5 inertia switch. HTH Mo Quote Link to post Share on other sites
Bowie69 1,443 Posted January 6 Share Posted January 6 RRC one works, sits under the passenger seat, I use it to disable the truck from running if I have left it in a suspicious looking area.... Quote Link to post Share on other sites

So you can activate the switch manually? As I recall you can't do that on the later (td5) type. Quote Link to post Share on other sites

Mo Murphy 717 Posted January 6 Share Posted January 6 The TD5 one can be reset by pressing the button on top but it cannot be activated manually by pulling out a plastic button. The only way to activate it is to shock it by shaking or impact. Mo Quote Link to post Share on other sites

Is that shaking or impact Ross ? 🤣 It does take a bit more effort than you'd imagine and I can't see it lasting long if you were to thump it everytime you wanted to use it as a security device ! 😵 Mo Quote Link to post Share on other sites
landroversforever 866 Posted January 6 Share Posted January 6 I've set a D2 one off deliberately and it didn't take much of a thump. Certainly wouldn't think it would damage it. Quote Link to post Share on other sites
Tanuki 135 Posted January 6 Share Posted January 6 Rather than an inertia-switch [which can be set-off inadverently - the one on my 90TD5 tripped once during a 'clumsy' trailer-hookup] could you maybe use one of the 3-way oil-pressure-switches that kill power to the fuel-pump when there's no oil-pressure? Alternatively, 1970s/80s Fords used a relay that took pulses from the distributor and shut-down the fuel-pump when the engine wasn't turning. Quote Link to post Share on other sites
