I have replaced the alternator in '74 1.8 and put all wires back in place where they were. Now at start up, the alt light glows on the dash until I rev up the engine a little. Then it goes out and stays out. Any cause for concern? Fan belt maybe not tight enough? Would appreciate any thoughts / ideas. Thx.

When is the last time you had the voltage regulator checked?

The Cap'n (IMG:style_emoticons/default/agree.gif) On my /6, it's around 2000 rpm. As long as it stays out afterward, all is gud ... (IMG:style_emoticons/default/bye1.gif) Andy |

My thanks for the replies. That's exactly what it is doing. After the revs get over 1500 on the first tap on the accelerator, light goes out. Glad I don't have to take the alternator back out. Not fun.
