I would sure hate to lose power, I love throttling around my truck, It just can't stay away from 75-85Mph. BTW, How about headers?

In model railroading DD> we often use such an arrangement to detect OVERLOADS and SHORTS, but DD> not an OPEN. Here's another scheme that just crossed my mind. It requires the use of a "ganged" switch like a a double-pole double-throw switch. The switch can be divided into two parts that I call A and B. The idea here is to use a switch so that in one position, part A is open and part B is closed. In the other position, part A is closed and part B is open. Look at the sketch below and you'll see the A part of switch S1 is open while the B part is closed. This would be the state if the headlamps were switched off. Think of S1A as the headlamp enable and S1B as the LED (D1) enable. Below you'll see at the left the 12 volt source (battery) that allows current to flow through R1 and through S1A (if it's closed). It makes more sense to analyze the two states of the switch. Let's call them state 1 and state 2. State 1 is where S1A is open and S1B is closed. This is the state pictured below. In this case, current is through R1. If the bulb filament is good (as is shown below with the cold resistance of 1 ohm), then the voltage across R2 (and the series combination of R2-D1) is about 0.050 volts. That is insufficient to activate LED diode D1. It is also insufficient to light the bulb R2. What if the bulb filament is open (burned out) and the switches are in still in state 1? In this case, you would open R2 and the voltage across the series combination of R2-D1 would be about 7 volts (I'm assuming a voltage drop of 2 volts across D1, by the way). This would provide about 20 millamperes of current through D1 and would signal a failed headlamp filament. R1 = 250 +-------------------/\/\/\------------------+ | | | | | / | | / S1A | +----------o o--------+------------------+ | | | + | | | --- \ \ 12 - / R2 = 1 / R3 = 250 Volts --- \ Bulb \ - | | - | | | | | | | | D1 S1B | +------------------------+---|<|---o////o---+ I'll not redraw the above circuit for state 2, but just pretend that S1A is now closed while S1B is now open. If the bulb filament was good, i.e., R2 = 1 ohms, then the bulb gets a full 12 volts across it and it illuminates. However, since S1B is now open, no current can pass through D1 and R3, thus preventing illumination of D1. Consider what happens if R2 is open during state 2. S1A is still closed and S1B is open. You will not get current through D1. As a matter of fact, you cannot get current through D1 when S1B is open, regardless of the condition of bulb filament R2. When the switch is in state 2 (closed S1A, open S1B), sufficient voltage is applied to bulb filament R2 to illuminate it. However, you will not have filament-detection capability in state 2. Only during state 1 where the headlamps are turned off will your have detection capability. --- QScan/PCB v1.19b / 01-0232 * Origin: IBMNet Connection - Indpls, IN - 317-882-5575 28.8 USR (1:231/1) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F2K00035 Date: 02/14/98 From: JOHN PUMMILL Time: 09:44pm \/To: JASON WEDEHASE (Read 0 times) Subj: New Car Weights JW> Don't you think it has anything to do with crumple JW> zones and JW> safety features and re-enforcements and all that crap?
