This has ben a VERY frustrating problem. I shall lay out all the steps I took to find the fault so as to narrow down the possibilities.
Prob- Brake lights do not illuminate when pedal is depressed... the bulbs DO work when connected to 12v supply on both parking light setting and brighter brake setting. Contacts are clean, sockets are making good contact with bulbs. Turn signals both work, and parking lights (both upper and lower light sockets) illuminate when switched on at instrument panel.
1. checked bulbs (L & R) - both working fine.
2. Checked socket contacts - both working fine,
3. wires leading to both sockets in tact and good connections / good ground.
4. 12 ish volts at lead to brake switch on hydraulic brake line junction. When brake bedal is released there is no current... 12v + detected when pedal is depressed.
5. disconnected hot lead to brake light switch and jumped to bulb with good result... then reconnected hot wire to switch and jumped output wire from switch to bulb (and ground) with no illumination. ???????
How could I detect a voltage coming through the switch and yet when the bulb is connected to it get no light?
WTH? that last "H" has an E and a pair of double hockey sticks with it.
