external voltage regulator / warning lights clicking

[1983hiacevan3y]

i have a problem with my hi ace van 1983. i replaced my alternator about 2 months ago. now my external voltage regulator (up under the dash on floor board) and all warning lights click on and off so quickly. unless i turn on my lights or indicator. i can drive van with lights of but when my revs are low it starts again until i rev it a bit. i have two spare ex/volt regulators that seem to check out good when i test their ohms following my manuals test steps.. when i plug them in they both click fast as well. wondering if they are all faulty or my new alternator or something else? wiring short? relay fuse?
wondering what to do next. every problem has a solution. i love fixing my van myself. so would like to work it out with your advice.. hope some one can help.. thanks.

p.s i have look at http://www.toyotavantech.com/forum/s...christmas+dash

Have you looked at the fusible link thread?

It's mandatory reading as well!

Most of us on this forum are from the US. Your charge system is a bit different from ours (all US vans have alternators with internal regulators). Because of that most of us are unfamiliar with external regulators. That being said, it's highly unlikely that 2 or more regulators would exhibit the exact same problem. My guess is it's either a defective alternator or a bad ground. Good luck. Tim

thanks i will check all fuse links and while im at it i will check all wires, especially the earths make sure none are eroded.
i have had problems in past with the warning lights and voltage regulator spazzing out. just never this fast. usually found the problem to be a wire worn through somewhere. blowing a fuse or the warning lights staying on. never continualy clicking very fast unless i turn lights on..
its raining now so i cant work on van.. will keep checking in and updating my progress.
