Hey all.
I have a 1987 300SDL. Had to buy a new antenna. Got a universal antenna. I'm having a problem with the wiring and need some help.
The universal antenna only has 3 wires. One Red, Black and Green. The wiring diagram says that the Back goes to ground and the other 2 will go to the wires that power the antenna.
The problem is this. I have tried many different connections and here is what I get:
1. Connection option #1 makes the antenna go up as soon as the radio is turned on. The antenna switch on the dash does not control antenna.
2. Connection option #2 does not make the antenna go up as soon as the radio is turned on. The antenna will go up, only when the antenna switch on the dash is set to the "max" position. If I turn the switch to the middle or "off" then it goes down. Did not like this optoin as it did not seem like the switch was to be left in the "max" position.
3. Connection option #1 makes the antenna go up as soon as the radio is turned on. The antenna will go down, only when the antenna switch on the dash is set to the "off" position. If I turn the switch to the middle it will go back up. Did not like this optoin as it did not seem like the switch was to be left in the "off" position. Also, can not raise the antenna say half way up rather than max.
So I'm very confused and I don't want to take my chances of burning out a motor or fuse or something because I'm not wiring it up correctly.
I really appreciate any help.
