Good job.
I still haven't found a suitable chirping horn for mine, but it's still on my list, and I have the wiring all hooked up. (maybe right after the water pump that is oozing). DG |

Thanks. The siren only chirps when unlocking & locking. Otherwise its quiet (even in panic mode). But it is better than the peizo which cannot be heard 5 feet from the car.
I also took the advice from Chris. Replaced the dome lights, reading lamp, and trunk lights with LEDs ! ! They look great and Zenon White is very bright. These were cheaper prices and shipping (about $30): Dome & Trunk Lamps (4): http://cgi.ebay.com/ebaymotors/1pc-42mm-211-212-214-HP-LED-Xenon-White-Festoon-Bulb_W0QQcmdZViewItemQQ_trksidZp1713Q2em153Q2el1262QQcategoryZ33713QQihZ011QQitemZ320223124451QQtcZp hoto Reading Lamp (this actually fits): http://cgi.ebay.com/ebaymotors/2pcs-168-194-Refractor-5-Power-LED-White-Wedge-Bulbs_W0QQcmdZViewItemQQ_trksidZp1713Q2em153Q2el1262QQcategoryZ33713QQihZ011QQitemZ320223124346QQtcZ photo The LEDs took about a week to arrive from Hong Kong. The relays are wired up for the "Radio ON til Door Open" mod. Planning to install next weekend. After over 12 years, this car is finally getting some actual creature comforts. |

AT long last, I have finally attempted at hooking up an Omega REC-11+ with the relay set up shown here (yes I wired two relays together ). Anyway, I hooked it up to the vacuum pump connectors on my 1987 260E and it kinda work. I press the lock button on the remote and sure enough, the locks moves down on all four door and the trunk. However about 1 second after it moves down, it pops right back up into the unlock position. What could I be doing wrong??? Thx in advance. |

The lock signal needs to be present for about 1 second or maybe a bit longer for some vehicles. If the omega unit you are using can be programmed, try setting the lock pulse time to about 1.5 seconds.......

Just looked more closely at the schematic you provided--I see you already have a 2 second pulse. Is there continuity between relay contacts 87a and 30 when the relays are not energized? (can you still operate the locking system with the key in the front left door? if so, you have continuity between these contacts)

Well this unit can be programmed for either 0.8second or 3second. So I current had it set for 3 second. |

I hooked up my multimeter in continuity test mode and it shows continuity from 30 to 87a (on both relay). I didn't check to see if the key still works in the front lock. But according to the circuit shown it should still works because when the relays are not energized current should flow through the blue pump wire as before. |

I'm not sure I can be of any more help.
One thing you might try is to manually activate the lock relay by grounding pin 86. Leave the ground on for several seconds. (maybe 5 or 6) If you have a successful lock, then you will know that your omega provided lock pulse is not long enough. I'll have to look at the lock logic description on the MB service CD--it might be possible that if you have a leaky or slow system, 3 seconds may not be long enough. Disclaimer: I ususally don't post unless I'm pretty sure about the issue at hand. In your case I'm not sure I have a good understanding of what your problem might be. The above suggestion is just a trouble shooting guess..... J. M. van Swaay |

IMHO, I think you may have selected another alarm setting incorrectly. IIRC, there is a remote double-pulse feature (sends 2 pulses from the remote); make sure its set to off. Otherwise, I would first test with the key to make sure the locks. This may help isolate your problem. If the locks still works normally, I would set the signal to the shorter length and retest (will require you to be closer to car for activation). If using the key dont work, then you definately have a wiring problem somewhere (probably in the relay setup). Note: I had voltage leakage from the alarm system causing strange things to happen. I installed diodes @ all power & device activation connections (see post #135) to counteract this and everything then worked as designed. Just another suggestion. Hopefully, you find your little electrical gremlin... Good luck! |
