Pontiac, Oldsmobile, Saturn, Mercury, Plymouth, Hummer & AMC Mercury Mystique Jump Post Location & Safe Protocol

📍 Step 1: Terminal Location

Battery & Remote Jump Posts

Engine bay (Pontiac Bonneville/G8 and Aurora have batteries under rear seat or in trunk with under-hood remote post).

⚠️ Step 2: ECU & Fuse Safety

IBS & Fusible Link Protection

Classic American cars and discontinued GM/Ford/Mopar brands often suffer from side-terminal battery bolt corrosion, VATS/Passlock security lockouts after low voltage, or vintage 6V/12V starter solenoid heat soak.

⚡ Step 3: Charging Check

Alternator Voltage Test

Post-boost verification of 60A–145A Delco CS130/AD244 / Motorcraft 3G Alternator output (13.8V–14.8V on 12V; 27.6V–28.4V on 24V commercial).
