Coulstock Posted January 4, 2019 Report Share Posted January 4, 2019 Hi all, My ammeter has just comeback from being refurbished and doesn't have the round (brass looking) screws that hold the spades in position on the back (i'm afraid i dont know the name and can't find any info on them) but my temperature gauge does have them. The ammeter was sent back to me with just nuts on the back and no spades. The firm sent the spades back to me but not the round screws and i can't remember if they were on the ammeter when i sent it to be refurbished or not. My Question is do i need them or can i just use the nuts on the spades ? I hope this is not a daft question but electrics are not my thing so i am trying to double check everything electrical!! Many Thanks, Nick Quote Link to post Share on other sites
Sapphire72 Posted January 4, 2019 Report Share Posted January 4, 2019 (edited) I believe the gauge on the right shows the backside of the ammeter, because it has the brown & white wires. Looks like you need the big bracket, two bolts/screws & two nuts. Edited January 4, 2019 by Sapphire72 Quote Link to post Share on other sites
Mike C Posted January 4, 2019 Report Share Posted January 4, 2019 You do. The nuts on the electrical spade connections shouldn't touch the holding bracket. Quote Link to post Share on other sites
Coulstock Posted January 5, 2019 Author Report Share Posted January 5, 2019 Thanks Guys, i have the holding bracket and understand it musn't touch the spade connectors. i am talking about the round nuts/screws that you can just see in the above picture on the gauge on the left, or can i use the ordinary nuts that are already on there.

Mike C Posted January 5, 2019 Report Share Posted January 5, 2019 I believe that the round, knurled nots are used because they are easier to tighten behind the dashboard. I see no reason to preclude normal nuts if you can tighten them. Quote Link to post Share on other sites
brian -r Posted January 5, 2019 Report Share Posted January 5, 2019 As Mike said above the two round knurled nuts are for holding the ammeter in place with the two L shaped brackets. The nuts will be fine for this as long as you have nimble fingers to get them started and have a suitable spanner to nip them up. Brian Quote Link to post Share on other sites
Z320 Posted January 5, 2019 Report Share Posted January 5, 2019 (edited) Hi Nick, I would like to recommend these "knurled nuts" for easy get them the instruments in and out, to find for example at Rimmer or on eBay, on my instruments they are M5 the high typ (very usefull), Rimmer says they are 5 mm (M5?) on TR4/4A and 4 mm (M4?) on TR6.

Coulstock Posted January 5, 2019 Author Report Share Posted January 5, 2019 (edited) Sorry guys i am not making myself clear. I understand about the knurled nuts and bracket. If you look at the picture, the gauge on the left has the green and black wire and the light green and white wire are coming off two spade connectors. If you look carefully they are held on by round brass looking screws. My temperature gauge has them but my ammeter just has nuts. These are what i am not sure about, do i need them or are nuts ok? Many Thanks Nick Edited January 5, 2019 by Coulstock Quote Link to post Share on other sites
Z320 Posted January 5, 2019 Report Share Posted January 5, 2019 to avoid any misunderstanding please post a photo of your instruments Quote Link to post Share on other sites
RogerH Posted January 5, 2019 Report Share Posted January 5, 2019 Hi Nick, you can use any suitable nut to hold the spade fittings in place. These are accessed with the gauge in your hand - so no problem with awkward to get shapes. Roger Quote Link to post Share on other sites
Coulstock Posted January 5, 2019 Author Report Share Posted January 5, 2019 I have tried to upload photos but am struggling, i will have another go tomorrow. I think Roger has answered my question, so thanks Roger. Quote Link to post Share on other sites
Z320 Posted January 6, 2019 Report Share Posted January 6, 2019 (edited) To get the cable tight fixed on the gauge better use a hex nut and a tool, not a knurled nut and your fingers. Edited January 6, 2019 by Z320 added "hex" Quote Link to post Share on other sites
