I'm going to have several electrical questions. 1st, Is pin #8, on the 14 pin plug at the relay board, the only switched 12v+ source in the engine compartment? TIA, Kent

Thanks for answering. Electrical issues remind me of how little I know. The blue wire enters as pin #2 on the 14 pin connector which goes to D+ and exits the relay board as a red wire presumably part of the alt harness. I wondered if I should ignore the blue lead or does it need to be connected to complete some ubiquitous circuit I'm unaware of. I do know the single lead goes to the battery but that's about all. (IMG:style_emoticons/default/lol-2.gif)
And now another issue. Last night I powered up the 2 main circuits which go to the fuse #11 & #27 steering column. One thing has me baffled. At first the turn signals worked all around. In fact all of the lights work including the pop up headlights. I noticed I had crossed a back up lite with a tail lite and corrected that. A few minutes later I was going thru the various components again and noticed the turn signals weren't working. No illumination at front or rear bulbs when the stalk was moved L&R. No flashing either. The PARK feature does work for the L & R sides and the flasher unit #47 works when the Hazard switch is pulled. (IMG:style_emoticons/default/confused24.gif) So this new question is twofold. Does the power go thru the flasher switch and/or turn signal assm first and then to the flasher unit OR the flasher unit first? 2nd; can the flasher unit work on the Hazard switch but not the turn signal? If I need to test the turn signal assm is there a procedure to follow? TIA, Kent |

(IMG:style_emoticons/default/lol-2.gif) Ok. All the wiring to/from the 914 alternator and VR will not be used including the GEN light. You really don't need to do anything with them if you don't want to. I hesitate cleaning up wiring unless absolutely necessary as you never know what else uses that wiring.

If I need to test the turn signal assm is there a procedure to follow? TIA, Kent 2nd question first, the flasher can work with either the 4-ways or turnsignal stalk. They are in parallel. I believe all the wires end up at the 4-way flasher. 1st question. See the schematic below. Power comes to the flasher first. The red wire from the 4-way switch is just so the 4-way switch can power the flashers with the key off. I don't think the back up light fix should affect the turnsignals working. Sounds like something else in and around the steering wheel and turnsignal stalk is at issue. If both the L and R turnsignals quit working, it sounds like a connector between the steering wheel and the flasher has come loose. Attached image(s) |
