1946 Super Deluxe...
Bought the car recently and it had aftermarket wiring and turn signal system.
I removed all the wiring because it was done poorly and cheaply.
I bought new original style harnesses and removed the turn signal system.
The PO installed dual contact front parking light sockets and used Sylvania 90 bulbs. These bulbs are dual contact single element.
My problem.....I have power to one of the contacts in the socket and ground to the socket housing. The bulb does not light up (new bulbs).
I jumped power to both contacts in the housing and still no light up.
I removed the bulb and went straight to a battery with test leads and no light up. I also tried powering both contacts on the bottom of the bulb at the same time.....nothing.
I have 4 different bulbs all act the same. I have a 1158 dual contact dual element bulb and it will light up one element when installed in the socket.
The alignment pins on the socket and the sylvania 90 are in the same line 180 from each other, no offset.
I could just buy a single contact socket and change it out, but Im curious about this issue.
The Sylvania 90 did light up when used in the turn signal system, but I dont remember if it lit up in the "parking" position.
Again its a dual contact single element bulb .......weird
