Integrated Voltage Regulator in the dash Reply #15 – October 29, 2009, 01:39:35 AM i would venture to say the small winding in there could be observed as a possible shunt resource. should power this up and see what i get.problem is i dont know what my baseline milivolt would be although i would know the mv drop, nor what ampacity the possible shunt would be.i have often wanted to fab up a shunt for our cars, its such a simple concept, i deal with them all the time.im not saying its a shunt,, just its possible it might be one by default.The oil pres sender is one item i dont have dospoogeented in my diy,,, may take time tomorrow to get that for you. Since i have a full digi cluster, the oil data is coming from there so now i have to figure out where its at. Quote Selected
Integrated Voltage Regulator in the dash Reply #16 – October 30, 2009, 12:29:20 AM manual 33 05 35 test point TS3 says the resistivity of the "sender" should maintain a resistive value between 9 and 40 ohms while reving the motor a little back and forth.I was actually interested in finding out what primary piece part manages the oil bar graph and did not find my answer. Apparently the sender does.I found no hint of a sensor though. Quote Selected

Apparently the sender does.Do you think the bar graph in full digital dash? I think it should work like an electronic EVmeter - it reads voltage on some resistor and compares it with values for low and high pressure, so the pressure sender could be same as for buttstuffog dash.

I was just commenting on the full digital cluster.The other options on our cars is a single oil light. In this case, the oil sending unit is just an "on" or "off" switch and nothing more.

Integrated Voltage Regulator in the dash Reply #19 – November 01, 2009, 08:05:40 AM Sorry, my mistake. Edited.Yes, I know about all 3 options. If the change of IVR won't take effect I'm going to make half digital dash by myself with microprocessor and small LCD. Quote Selected
Integrated Voltage Regulator in the dash Reply #20 – November 15, 2009, 12:41:46 PM So, I was yesterday in the garrage and was trying to measure resistances of senders. Unfortunately, I couldn't start the engine, because I have the battery in another car, so I have some numbers from staying car. oil pressure sender ... > 200 Ohms*temperature sender ... > 200 Ohms*fuel amount sender ... 36,5 Ohms*out of 200 Ohm range - I didn't remember the exact positions of each sender contact and didn't try higher ranges, because there were a lot of lower numbersI think, that there must be some fault, because resistances over 100 ohms are out of ranges. Or not?Here are all numbers I measured. Dash means resistance over 200 Ohms.-....-....12,4...3,6...3,6...36,5.....-......-.......4,9-...8,8...2,6.....3......3.....3,5....5,3...2,6....197,8And finaly, I decided to open the IVR. It didn't do anything until I loosened the small screw. It didn't have enough force to bend the bimetal, so the contacts were still connected. Here are some photos: Quote Selected
Integrated Voltage Regulator in the dash Reply #21 – January 20, 2010, 10:03:55 AM I've finaly made the electronic IVR. This is the testing version. 78S05 is enclosed into the original IVR body. Here is a photo :) Quote Selected

Integrated Voltage Regulator in the dash Reply #23 – January 23, 2010, 06:23:35 AM Quote from: jcassity;307521whatcha got there for parts?I'm not definately sure if you're asking for the price or components, so I'll write both.78S05 (5V stabilizer, up to 2A)two capacitors (10 uF and 100 nF)couple of wires, some bolt and two nutsSo complete repair cost me 15 Czech Crowns (it's little bit less than one dollar) :) Quote Selected

Integrated Voltage Regulator in the dash Reply #26 – February 20, 2010, 11:01:39 PM Hey Gang,I havn't gotten around to my V6-V8 swap yet,still building the engine and tranny ect.My digital dash V6,87 Bird has a temp guage that's inop,no check engine light but car seems to run rough and rich,made me think it may be the temp sensor? Well I tried a new one along w/a tested T-stat and still nothing.Any ideas? I'm not an electronics guru. Have the basic understandings but any ideas are welcome. Quote Selected
Integrated Voltage Regulator in the dash Reply #27 – June 20, 2010, 06:17:15 PM Hey Guys Just for an update. This is sold on ebay for 20 dollars and it comes with no hassle warranty.item number 270595341050[/IMG][/IMG] Quote Selected
