UP-DATE: I received two more of the gauges yesterday and got them installed, the voltmeter, and oil pressure gauges. The new oil pressure gauge uses a 0-150 psi sending unit that's powered by 5V DC from the gauge itself, and has it's own ground wire (a three wire connector). The stock Harley sending unit is a 0-60 psi unit and is powered with 12V DC and is grounded through the unit itself, and uses a different connector (a two wire connector). Since the sending units differ in their psi range I have to use the sender that came with the gauge for it to be accurate. By using the sender and wiring harness that came with the gauge however would mean I'd loose the low oil pressure idiot light on the dash of the bike because I wouldn't be able to use the stock wiring due to the voltage difference, so what I thought I'd do build a regulated power supply to drop the voltage of the stock wiring from 12V to 5V and install this in between the stock wiring and the new gauge. The regulated power supply I built worked fine and the gauge worked just as it should, however the idiot light still didn't illuminate through this circuit like I was hoping, which really isn't that big of a deal, I was just hoping to keep full functionality of this circuit, but since this didn't restore the idiot light function like I hoped, I decided to abandon the regulated power supply idea and just run the new harness to the gauge and cap off the old one at the sending unit and live without the idiot light. Here's the latest photo of the gauges as of last night. I'm still waiting on the oil temp gauge because Prosport was out of stock on this particular one, so I had to order it from a different source.
since the gauge has some kind of electronics to light up the segments, wouldn't it be nice if they flashed when it got down to 5 psi or something?
have you thought about t-ing in another sending unit to make the idiot light functional?
Yes, you'd of thought they'd have done something like that, but its not the case. I have to admit I didn't think of tee-ing off and running both sensors. The thing that concerns me about this idea though is having that amount of weight (two sensors and a Tee) then thinking about the stock sensor (which is about 2-1/2"to 3" long) combined the length of a tee fitting, would have things hanging out there quite a ways, combining this with the vibration of the engine I'm thinking it could possibly put to much stress on the fitting over time and causing it to eventually fail. I'm still thinking about other alternatives but at this point I'm thinking there's not much I can do about it short of putting in a Tee like you say, I'm just concerned of over stressing the fitting though, I'd hate to have it fail in the middle if nowhere.
I guess one option I could go with is getting something like this http://prosportgauges.com/oil-filter-adaptor-plate.aspx and putting the sensor for the new gauge in this and just leave the stock sensor in and connected as normal. I wonder though if that would be the best place to monitor for oil pressure on a Harley engine, what do you guys think ? I'm not sure if I'd have the clearance though to spin something like this on.
I did examine the idea of using a tee and mounting both gauges off the same port, I found by doing so it puts the stock sender to far forward to where it contacts the frame tube. I thought about coming off the top of the tee with the stock sender but there isn't enough length in the stock wiring harness to do it, so these issues combined with my concern of the failure of the fittings that I mentioned before, I decided to abandon this idea.
Here's what I ended up with on how I'm going to do this, I decided to get one of these http://www.ebay.com/itm/290888457708...%3AMEBIDX%3AIT It doesn't need to be spun on like the one I mentioned in my last post so clearance shouldn't be an issue. I'll mount the oil pressure sensor for the new pressure gauge in this and leave the stock pressure sensor in its original location and connected back up, this way I'll still retain the idiot light function, which like I said isn't that big of a deal, I just wanted to keep full functionality if possible. Since this has multiple ports, I can also mount the oil temperature sensor in the same location instead of the bottom of the oil pan. Does anyone see any potential issues with going this route ? One other question I have, is if anyone knows of the oil pressure is tied into the ECM ? It doesn't appear to be to me because the bike starts and runs like normal when I start it, but I haven't had a chance to take it for a ride yet because I still have it pulled apart waiting on the other stuff I have ordered. If so, that's another reason to retain the stock oil pressure sensor.
UP-DATE: Well I finally had a sunny day where I could go for a ride and try the gauges out, and regrettably they are just to difficult to see in full sun light, to bad because they look awesome at night. Oh well, I have other vehicles I can use them in so it's not like I bought them for nothing. So what I ended up doing and what I probably should have done in the beginning is buying the Dakota Digital gauges from these guys. http://www.ebay.com/itm/HARLEY-TOURI...510555?vxp=mtr I paid $919 with free shipping but they've since re-listed at the higher price of $931 which either way I think is a good price for them. Soooooooo they're supposed to be here tomorrow and I'll install them then and post some photos when I'm done. I want to thank everyone for their help even though it was basically for nothing, but it was still fun to try. Oh, and one other thing, that Glow Shift Oil Filter Sandwich Sensor Adapter fit on the bike fine however it moved the filter so far back it hit the cam positioning sensor where you couldn't get the oil filter on, so if you're thinking of getting one of these for your bike.....don't, there again I have other vehicles where I can put this to good use along with the gauges. Thanks again guys
as I was reading your posts I was going to toss in a remark about Dakota Digital, but now that I have read 4 pages I see you found them yourself.
Nice stuff, and worth every penny, and that is a lot of pennies.
Yes, I've known about Dakota Digital gauges for quite a few years, I've had one on my Softail for about 15 years now and I love it. I was just hoping I could find a cheaper alternative, but oh no.
Well, got my Dakota Digitals today and installed them. The install went pretty good and was fairly easy, it took me a little bit to figure out the set up on them but once I got it figured out it went pretty quick. Now if it would just warm up a little more I could take them for a good ride. The numerals are pretty big and easy to read and they seem like they'll be more than bright enough on a sunny day, now if we'd just have a sunny day. Here's a photo of them on my bike.
