tcbaurpower 5 Report post Posted October 8, 2010 Hey a quick question. I got a manual e28 with a diff that has seen better days. I have a spare diff but it was from an auto e28 which I was thinking to just swap in. Will the ratios stuff anything for the manual gearbox?

tire 10 Report post Posted October 8, 2010 When replacing front brake rotors (with barely used second hand ones), do you need to sand the pad or the rotor or both or none? And what grit paper? Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2132 Report post Posted October 10, 2010 depends on how worn the brake pads are really. If they are sweet, just make sure the piston is pushed all the way back in the caliper and should be good. if not then might as well replace the pads while your in there Quote Share this post Link to post Share on other sites

Jacko 2154 Report post Posted October 16, 2010 (edited) Picked me up a new power aerial for the E30. Bit confused, its probably simple though. The original (aftermarket motogard) aerial has two wires, red and black. They were reversed at a connector though, red-black black-red. Aerial has never worked when ive owned it. Playing with a multimeter shows that red is earth (explains the reversed wiring...) and black seems to be dead whatever happens. New aerial has 3 orange wires too a relay, then a red and green wire. Tried plugging red-black green-red, nudda. Can someone point me too a generic wiring diagram for a 2 wire power antenna? I assume the red wire should go to the headunits power aerial output, and the green too ground? The relay is some sorta reversing thing? maybe current sensing and then reverses?

_ethrty-Andy_ 2132 Report post Posted October 16, 2010 two of the wires going into the relay are power and earth, and will be on the loop that the wires on the other side of the relay are in. the third is the signal from the head unit. in other words, when there is signal from the headunit, this shuts the relay and makes a continuous curcuit between 12V at the battery, through the motor for the aerial and then to earth/0V on the battery. like this, except the motor on the aerial replaces the light bulb, and the signal from the stereo replaces the switch http://www.radioelectronicschool.net/files...loads/relay.gif Quote Share this post Link to post Share on other sites

Relay has two inputs Red and Green, and 3 soldered output wires to the aerial - Ground, Up and Down I guess. So Ive only got two wires to plug in. It must use the + output of the headunit too drive the aerial up and down, and the other wire must be ground? I guess the relay has some sorta latch and is only used to control stopping, starting and reversing the motor in a cycle.

Both my power antennas have a power wire that goes to the battery / ignition whatever you want. Then the other wire goes to the head unit. Quote Share this post Link to post Share on other sites
Jacko 2154 Report post Posted October 17, 2010 Both my power antennas have a power wire that goes to the battery / ignition whatever you want. Then the other wire goes to the head unit. Just figured it out. The relay mounting bracket supplies the ground, its sneakly soldered to some of the relays terminals. Red is +12V Green goes to headunit. +12V on the green wire switches the relay, antenna goes up. OV on the green wire switches the relay back and antenna goes down Quote Share this post Link to post Share on other sites
