MG TD TF 1500 - Running without Amp Meter for repairs

My Amp meter stopped working, but the red light is only on at low RPMs so I think the system is working fine. It is pinned to the negative side. It starts and runs fine.

I would like to send my gauge out for repair, but am wondering how best to continue to drive the car. It is my daily commuter. Can I just take a bolt and connect the two cables together and wrap it in tape?

Larry - It won't hurt to run without the amp meter at all, just bolt the two leads together as you suggested and tape it up real good (disconnect the battery from ground before fussing with the wires). Before you remove the meter, you might want to tap on it with a screwdriver handle (just like on the fuel pump) and see if that corrects the pegged reading. The meter is a very simple device with a single loop of heavy gauge wire and a magnetized vane on a pivot for the needle. I suspect that it just got stuck to one side. Cheers - Dave

Sometimes procrastination pays off. Dave was right. A couple of days later the needle came unstuck, and it is working fine again. I didn't get around to trying his idea of tapping it harder with a screwdriver.

Larry ,
Don't forget the "original tool kit" came with not only a screw driver for "tapping", but also a small hammer for more stubborn problems!
(Works well on starters!)
