T-Series 1972 MGB Hazard switch.

Hello,

I bought a used hazard switch at Carlisle. Is there a way to test it before I try to install it? If so, please explain.

Thanks,

Chris

The simple way to check it, is to use a continuity tester(if you do not have ohm meter) you can get a 12 volt model at any parts store. Put alligator clip on one terminal, put probe on other, operate switch and light should go on and off.

Sorry, need more information. This switch has 6 contacts on the back of it, 5 connectable. Is it doing more than just on and off, and what contact does what?

Thanks again.

With 6 contacts I would assume it to be a double pole double throw switch which would be 2 separate switches on a common button. Each side should have its own common lead and two other contacts. One normally open and one normally closed. After the switch is turned on the N.O. would become N.C. and the previously N.C. would become N.O. with respect to the common lead. Without going out and disassembling my switch, that is the best I can do.

Assuming that it is the same as my '74 that I had appart last year, the switch is rather unique. It has a single power lead that is switched to power the other circuits at once...I recall once line each to the the rear signal lamps, one for the front lamps a another for the side markers. I woould suggest the following steps:
-Using a continuety tester, find the pole that should be the power and see if it has a closed loop when the switch is in the on position...then test each of the other connections to make sure they have the same reading.

Changing the switch is not really that difficult...unscrew the screws holding the plastic console to the metal frame (two on each side of the radio mount) and pull the entire assembly, radio and all, forward enough to get a hand into the back of the switch, release the retaining clip and pull it out.

Of course, the new switch is installed in the reverse order /ubbthreads/images/graemlins/grin.gif
