charging problem

New to this place. Very cool.

Just put in a new 160ah alternator. Originally had a 75 I think? It would drop out when everything was on.
The new one seams to do the same thing as the old one. It just cannot handle a load. Checked the grounds, getting an amp meter today to check and also I think there is a fusible link inline with the alternator to the starter relay??

Is there anyway to jump out the regulator to have it put out max power to see what it does? I was reading in my chiltons to jump out the regulator but it says for an external one.. Any help?

I used to have all kinds of electrical issues, then I discovered that my engine grounding strap wasn't tightened down. Now it's much better.

Check your ground, and Also::: Upgrage your Wire!!!!!!!!
If its the same wire that the old one was connected to. Current is flow of electrons...... wire is the pathway. If you want more flow, you have to increase the pathway. I saw it in a tech article once, but I cant remember where... Anyhow, I recently got a 4awg wire from my Alternator to the starter relay, and all my electrical systems work better. even my windows go up better now. All you need is an 18" jumper wire from your alt to starter relay. Thicker wire the better, and upgrade your ground, check for looseness and tighten if neccesary.
