I have an 84 GL that I am debating what to do with. I just had my mechanic check it out. The only major thing it needs is an AMM. I tested it myself with the Haynes manual test. Resistance between pin 6 and 7 is supposed to be 3.5 to 4 ohms. My tested 4.5. The other test is pin 6 to 12, which is supposed to have a resistance between 0 and 1k ohm. Mine registered 980. The car had been off for about 10 minutes. I don't know if that matters or not. Anyway, does anyone know if the 4.5 ohm reading is enough to mean the AMM is actually bad? I happen to have another 84 240 I'm not driving with the same AMM. Is the switch easy? How delicate do I have to be? If I decide to buy a replacement, should I just get a used one? I thought I heard someone say the reman ones are not a good idea. Does anyone out there have any experience with that? Is there a more thorough test that can be done in a shop?
Any input appreciated.
