Our take on the New 1 Wire Self Exciting Alternator High Output 120A compatible with Pontiac Buick Cadillac Chevy GM 350 SBC BBC 10SI Replacement#7127SEN, 334-2114, ADR0173, ADR0325, ADR0335, 400-12370, 20-102-7

A new 120-amp, 12-volt Delco 10SI-style alternator with a built-in regulator and one-wire self-exciting hookup. It fits a long list of 1960s and 1970s GM cars, including Pontiac Firebird, Grand Prix, LeMans, Bonneville and Catalina. The 120-amp output is well above the 37 to 63 amps of the stock 10SI units, which makes it a common upgrade for cars with added electrical load. It is a direct-fit replacement for the listed part numbers, so it swaps in without rewiring the charging circuit.

Questions and answers

What does one-wire self-exciting mean?
The alternator starts charging on its own once the engine spins it, so you run a single charge wire to the battery. No separate exciter wire or indicator lamp circuit is needed.
Is 120 amps too much for my car's wiring?
The alternator only supplies what the car draws. If you add high-load accessories, check that the charge wire and fusible link can carry the extra current.
Will it fit my Pontiac?
It is listed for many 1967 to 1983 Pontiac models, including Firebird, Grand Prix, LeMans, Bonneville and Catalina. Match your engine and bracket setup to the 10SI case before ordering.
Does it come with a pulley and fan?
Yes. It ships as a complete unit with a V-belt pulley, internal regulator and internal fan, ready to bolt on.
What is the rotation direction?
It turns clockwise, the standard direction for a Delco 10SI mounted on a small-block or big-block Chevy and the listed Pontiac engines.
