Alternator swap TVR T350

Thanks to advice from LeeT350c I manage to fit a new alternator to my T350 this week. I have put together a rough guide on how to do it for anyone who may need a little guidance. I have tried not to go into too much detail, so if anyone wants to add anything then feel free.

Approximate Time – 2 hours

Firstly jack the front of the car up on the passenger side and remove the wheel. Then remove the inspection panel to the rear of the wheel arch to get to the battery. Disconnect the earth cable from the battery.





The alternator is located under the air box, so the next step is to remove the air box. You will need to remove the upper and lower parts of the air box.




Now you have access to the alternator disconnect the B+ and D+ cables.



Now loosen off the 3 mounting bolts. There are 2 bolts close to the block which are very fiddly to get to. The other is on the wing side of the alternator, which is used to tension the belt.





Once these are loose you can release the tension from the belt and remove it.



You can now undo the 3 bolts fully and remove the old alternator from the car.

It is now a good time to attach the diode to the loom. This is attached to the D+ cable labeled alternator.
There should be plenty of loom to play with. Cut the cable about two inches from the ring connector. Strip the insulation back on both cut ends of cable ready for soldering. You now need to solder the diode into the loom. The Grey/Red end of the diode needs to be attached to the alternator side of cable and the black/white side of the diode to the loom side. Once attached cover with insulation tape or heat shrink.








The pulley wheel on my new alternator was different to that on the old unit, so I swapped them over. To stop the alternator spinning I used a screwdriver and wedged it in the blades.






Now you can fit the new alternator in place. I swapped the two rear bolts around so the nuts were on the outside. This made tightening them much easier. Do not fully tighten the bolts as you will need to tension the belt once in place. Refit the belt. Once the belt is fitted lift the alternator upwards to add tension to the belt, and then tighten the 3 bolts. An extra pair of hands would make this job a lot easier.



Connect the cables to the new alternator.




Now refit the air box and reconnect the battery and your ready to go again.
