EXU question

[Charles Hill]

I spent part of the afternoon getting the TC ready to come out of hibernation. Hopefully, Spring will soon be here in Kansas City. One of the items I was working on was replacing the tacky inline fuse for the horns with the proper Lucas fuse block. I bought a replacement from Abingon Spares a while back, but never got around to putting it on. The only problem is that I couldn't figure out where it is supposed to go. The only logical location I could find is there is one hole where the lower hole for the Oil can on home TCs is located. Problem is that the fuse block has 2 mounting screws. I checked my Lucas TC parts list and it calls for a fuse block nr 37107. Abingdon sent me a unit numbered 37130A. It looks like the picture of the 37107 in the parts list. Possible conclusions: 1. Abingdon sent the wrong part and the 37107 uses only one mounting screw. 2. Early EXUs didn't have a horn fuse. Mine is 7387 and the first, of course, was 7380. 3. The fuse block is mounted somewhere else that I couldn't find. My firewall has some extra holes - for instance the ones where the Ford starter solonoid was mounted when I bought the car, but none match the pattern of the holes on the fuse block. And I couldn't find any evidence of welded over holes. 4. The factory only used one of the 2 mounting screws for the fuse block. Anyone have information that would help? Regards, Charles Hill

Hi Charles, The Lucas horn single fuse box mounts with two bolts on the side of the firewall just in front of, and below, the voltage rregulator. It has two screw wire connections on one side of the fuse to feed each horn and a single power feed screw connection on the other. I just wired my EXU horns on TC-8654 EXU this weekend. If you need more details on location I can measure the exact hole location. I assume you have the correct EXU firewall which has two reinforcement channels on the inside of the battery box and the twin horns bolt through this reinforcement. Now another question, does the EXU horn push simply ground through its mounting bolts/contact with the metal dash center? My horn push has only a single wire connection for the horn. Pushing the button grounds the switch itself and completes the circuit. Seems a bit Mickey Mouse, but maybe that's the way MG built the car.

Bob, The fact that I might have a different scuttle crossed my mind. I saw the reinforecements behind the horn when I was looking for possible evidence of welded up holes. It didn't register that the scuttle on the 46 didn't have the reinforcements in the battery box. If they are only present on an EXU, then I do have the correct scuttle. The fuse block is exactly as you describe. I've got it mounted by one screw on the front of the battery box. I suspect this hole is for the cable clip for the horn wire. I can't find any holes on the side of the battery box other than the ones for the horn and regulator. Any ideas of where the holes went? I can't find any evidence that someone welded them over, but its possible. Could my car have left the factory without the fuse block? Regards, Charles Hill

Does this help?

Charles, My TC had a two screw hole Bakelite thingy mounted on the upright timber that joins to the bulkhead on the driver's side. The bottom screw hole was 3" above the floor-board. I hadn't a clue what it was for as there was only a short length of single (armoured!) cable coming from it. I suspect this is what you have a hold of. David Lodge Charles Hill wrote:

Hi Charles, I believe the reinforcing channels are only on the EXU cars and are there to support the horns. The fuse block is a Lucas Model SF5/2, it has various part numbers. I have a complete spare which has number 385175, 11 48 on the body. Another one has 385184, 3 47 on the body. Apparently same SF5/2 unit but with different fuses. The unit cover measures 1 1/4" x 2 1/8" vertical. The lower offset bolt hole on my car is 3 3/8" below the bottom horn mounting bolt and in line with the horn bolts, ie 5/8" back from the front face of the battery box. Location of the upper fuse holder mounting bolt is highe4r and to the left due to the offset of the bolts. I have owned my TC-8654 EXU since 1967 and it was a very original car when I bought it. I believe the location of the fuse block is correct being on the side of the battery box. I used the two holes on the lower front of the battery box to clip the horn wire feeding the LHS horn. To feed the horn, I used a short piece of brown wire from the voltage regulator terminal "A", this gives a direct feed from the battery but does pass through the ammeter. My wiring harness did not have a solid brown wire #33 feeding the horns directly from the battery. No idea if the car left the factory without the fuse block but I doubt it.

Mike... Keep cool!!!! The risers bow out and they are bolted to the outside of the spare tyre carrer. There should be a small spacer the same thickness as the foot on the spare tyre carrier so the riser is kept parallel with the frame. It goes in front of the spare tyre carrier. The spare tuyre carrier uses the two rear holes the spacer the two front on each side not as uou suggested the two in front.... J "Michael L. Stokes" wrote:

TC EXUers, I have the rear bumper risers and I can't figure out how they fit on the frame. The 4 holes on the riser do match the holes in the frame, but the front two holes are used by the rear tire carrier. One could bolt the risers to the outside of the rear tire bracket then put spacers in the rear two holes, but this seems silly. Might be silly , but that's the way it goes. Spacers are in the two rear bolt holes. Also, the risers bow out. I assume they bow to the outside? Yes, they bow out from the chassis. The outer/upper ends turn in 90 degrees to accept the licence plate support angle iron and the bumper "S" brackets. Distance between the two bumper mounting holes to the bumper "S" brackets is 23 inches. Your brackets may need some bending to get it all to work correctly. If not, it appears they bind the rear tire. However, the holes in the bracket the risers bolt to do not align if the risers bow in. I'm so confused!! I'm confused with what you are describing Regards, Bob Grunau TC-8654 EXU

Gents and Ladies with EXU models... What is your use (and possibly the correct use) for the hole that is right behind the near side horn mount on the batt box?? Thanks, Bill Tantau TC EXU 7606 PA 1688 PB 0530

[Koesten, Stewart]

I believe there was a hole in the EXU where a former style (used on TA/TB) voltage regulator used to be. Stew TC EXU 8862 KC
