Hi everyone I reversed engineered the ACU Test Box RH8851. I made several specimens, six (6) total to date. I use one of them to successfully test and adjust the ACU on my 1977 SW II LRF32027. A few years ago I shared the information with Vlad, however I don’t know if there were any interest in the box on this forum. I have a basic wiring diagram from which I successfully assembled the ones I have here in California. I’m willing to share all the information about the test box for the benefit of all. This is my way of saying thanks to all the folks who’ve posted information on this forum from which I benefited. I certainly don’t need to have six of the test box sitting in my garage gathering dust. Therefore, if anyone is in need of a test box I could list it on the For Sale section of the forum. I’m also willing to let anyone who’s interested in the wiring diagram and a complete parts list if you’re up to building your test box. Word of caution: it involves quite a bit of soldering…a lot. The enclosure for the test box is an off-the-shelf ABS box that is available online. If you prefer, you could make the enclosure out of wood. As for the face plate, careful placement of the holes for the switches, panel meter and potentiometers will take some effort if done from scratch. I have a template for the holes I could share. A company that does screen printing either on matal or ABS can imprint the names of all the bits. I don’t know if the test box is available anymore. About ten years ago, Albers were selling them for close to $2000 USD. I’d have to sit down before calling them for an updated price for the box. If anyone has a question about the test box feel free to respond publicly or PM me. Patrick LRF32027 | ||

I was just looking at the original post yesterday. I would love to have a copy of the circuit. I find myself in a situation where I need RH8851 and RH9884. Not sure if there’s a circuit available for the latter? Not sure what the cost of getting one you prepared earlier to Aus but it would be useful for our club self help days | ||

Hello David and Mark. Thank you. David, the patch cables for the test box are MIA somewhere in my car garage. As soon as I find them I will make some of them available on the for sale section of the forum. Mark. I'm willing to donate one of the test box for your club self help days. If you or anyone loves to twiddle with switches and knobs, the test box is for you! Lol. You will have fun using it as you follow the troubleshooting/calibration procedures in the shop manual. please send me an address and I'll get one off to you down under. I will go to my local post office and get a quote for the postage and get back to you. I'm not sure about Customs duty when it reaches your destination. By the way, I don't have a wiring diagram for the RH9884. I'll try and attach a few pictures of the test box I have on hand. Patrick LRF32027 * I made several attempts to upload the wiring diagram and some pictures of the test box to no avail.. I shrunk them to under 400kb and I continue to get an error message stating that the file size exceeded 800X800 kb. hands up in the air. | ||

Wow Patrick, what a generous offer. PM sent. The seeds of the RROCA self help were planted decades ago by Bill Coburn. The Victoria branch mantle was taken up by Robert Wort. Through the generous donations of one our members, Lionel Gell, we now have a workshop at our disposal. Once a month we get together to tinker and talk about issues affecting our old cars. I'm sure Patrick's magic box will be a great asset to our like minded enthusiasts. Thanks Patrick | ||

Gentlemen I’m trying to do a follow up contact with MARK HERBSTREIT. I had offered one of my ACU Test Box to his local group in Victoria. I’ve made several attempts to contact him but to no avail. Could some on this forum let him know that Patrick McGlashan is trying to contact him and is ready to ship the test box to him. Regards Patrick LRF32027 | ||

Hi Patrick. I'm here! I'm not sure what's going on with our telecommunication glitches. I got the pictures you sent on 9th July and responded same day. I just noticed a message from you in my gmail account from last night. I will respond to that now and see how we go. Cheers, Mark | ||
