How good are Chinese products
China is the way of life for the US now,It started in the 90's when large parts stores,found out that they could buy pallet loads of China products for less than half the price of US units,they were so cheap they could offer lifetime warranty's,replace bad units three time and still make a profit.So are they good? yes and no,even a cheap,crap,new starter or alternator will probably last at least a year in normal duty.I not only sold them in my shop,I installed them, did not want to do that twice under warranty,so I paid the price and bought the best,all have a higher copper ratio then the units of today,but who cares, it,s about price right.
Hooking a battery cable to a 50's to90's GM starter solenoid
When connecting the positive battery cable to the large top battery terminal on the starter solenoid after installing the starter on on GM engines of this era,usea socket on the big terminal nut,instead of a open end or box wrench,because,the wrench tends to hit part of the solenoid where the terminal tab goes and break it off.Also do not over tighten this stud or you may break the plastic cap.
What are the three terminals on a GM starter solenoid cap
The big teriminal,of course is for the positive battery cable.
The two smaller terminals are marked R and S. The S terminal is for the starter switch,the R terminal is hooked directly to the positive terminal of the coil used with points distributors,bypassing the coil resistor to momentarily supply full 12V to the coil in the start mode ,to help the engine start faster.
What is better?,Rebuilt or New
That depends on the rebuilder,and the quality of the parts they use.For new Alternators and Starters,it depends on the quality of the factory.But generally I had less problems,with my rebuilt units over new units.I believe that was because the metals copper,steel and aluminum,were better quality(purer)and used seasoned electrical parts,but thats just my thought.
Let,s face it, do you really care about a over the Internet warranty,the question,is my stuff good,answer,Yes it is.If your unit were to fail,how much does it cost to pull the unit out and send it back,cost is more than the unit is worth,so my stuff has to be good if I want to keep selling. I have a 30 day money back return,I have found out in over 10 years of rebuilding and sales, 95% of all units fail within this period.I also offer longer warranties on some units I know I can trust,
Should I fix or replace
Unless the starter or alternator has been badly abused,it probably is worth repairing,depending on what went bad.
Starter bushings are cheap and fairly easy to replace,but if gone too long, the armature can hit the field case and be ruined.
Starter solenoids,(screw on cap type) can usually be fixed one time for no cost by simply rotating the positive contact bolt.
GM direct drive starter brushes are easy to replace
Externally regulated alternators,always check the regulator first by disconnecting the regulator,and checking the voltage right on the alternator,usually 15-18v
Alternators: single plug GM's usually blow the regulators,that can be easily checked by sticking a pin in the back of the alternator to by pass the regulator.
