Obviously f**ked wiring but Any Ideas?

[Angkistrodon]

Previous owner was very mean to the under dash wiring.
When I turn on the blinker..my volt meter bounces along with the blinker.
New alt and battery, but it did this exact same thing before the first (stock) alt went bad. Any ideas on where to start looking?

How badly is the needle bouncing???

Barely bouncing (like inbetween 1 - 2 volts)???? Or a really big swing???

If it's the first one, it's behaving normally.... With the exception of those who have done big electrical upgrades (ie alternator...), EVERYBODY's does this....

2nd description..... Got me on this one... Have not heard anybody's needle doing this...

yeah...so Ang...after you're done putting in a bigger alternator in your's...how bout you come do mine? ;)

Happy to put a big alt in for you, I'll be over later tonight.

The needle only bounces 1-2 volts......So that is normal hugh?
Cool one less thing i have to worry about.

even using the 80 amp alt mine still swings a little when the blinker is on. its normal.
