Guys, Can anyone tell me if there are any shop manuals for the 2500M (74) TVR. I have a good TR6 Drive train manual that is helpful. Any advice you have will be welcom. Thank you for your time. Jerome

I have a M Owner's Manual and a Part's Manual. I believe both are available through the TVR Club. Not really workshop type manuals but the part manual is big and it does show you were everything belongs. That and a TR6 manual ought to do the trick

Gentlemen, Thanks again for your previous assistance. I have a new problem. My Tach on the 74 2500M doesn't function. I am unable to find a schematic diagram for its hookup. I thought that the 74 TR6 might be the same. However, no such luck. Can anyone tell me if there are any schmetics that show the wiring of the Tach. on a 1974 2500M. Jerome.

Perhaps this wiring diagram will help you.

I notice that the 2500M schematics don't show the tach. Is the 2500M electric or is it normally a mechanical one like on a TR6?
My '71 2500 has an electric tach, and the wiring diagram shows a white wire that goes from the ignition switch to the tach, and then a white wire from the tach to the + side of the ignition coil. There is also a Green wire (+12V) to the tach.

'71 Vixen 2500

Jim & Steve, Yes the tack is electric. Steve thank you for the schematic. The wiring that my tack has is like Jim has described, White wire in from Ign. White wire out to ? Green wire for 12 Volts. Again you Chaps have given me great assistance. I can only say,"thanks again". Jerome

Sorry, you're right that schematic was no help at all.

My '77 2500M is completely apart right now but I do believe it is a electric tach as Jim mentions.

I'd follow Jim's advice. I know that you need a "trigger", that would be the coil/dizzy wire. Plus a wire for the ignition - so if the ignition is on - the tach is on.

I wonder why the 2500M schematic doesn't have the tachometer connections in it? I'm betting that they just lifted most of it from the TR6, and forgot to modify it to show an electric tach. Hope you get yours working.
