Need help with alternator

[MARKDTN]

I was more concerned with making the original wire too hot and melting the insulation. If you have a 160A alternator where a 37A used to be and you add dual fans that pull 15-20A each running you may be in for problems. A 10Ga wire 4-7 feet is recommended for a max 65A while an 8ga is OK for 125A. I suppose 10ga is OK but seems marginal to me with dual fans-especially if it is 50+ years old. On my '83 K20 I added dual C4 Corvette fans and upgraded to a CS144. I ran an 8ga to the battery in addition to the stock wire and have had zero issues in almost 20 years. It already had a voltmeter.
