Most late model alternators are so tightly packaged into their cases (unlike the GM CS alts) that there is physically no more room in the case to upgrade the components. Other charging system problems include a loose drive belt, faulty wiring or blown fuse, defective ignition switch, etc. An Electronic Load Detection unit or ELD in the under-hood fuse block. com your online source for high output alternators. Since fuses restrict current flow, the fuse rating should be about 20% over the output rating of the alternator. There was a 160amp alternator on the 2005-06 models, but it is a 2 wire alternator, vs the 4 wire of the 145amp. Corroded or loose battery terminals are also bad news. Checking the alternator output voltage with a multimeter. Run engine at 2,000 rpms for tests and turn on the blower fan for the AC or Heater, the headlamps, and any other accessories that put a strain on the alternator, and watch the gauge to see if it decreases voltage or amperage. Slo-Blo feature eliminates nuisance blowing during temporary, short duration overloads. Don - Mo Lurch. It also controls the output of the alternator.

The bike What size fuse between amp and alternator should I be running? I am currently running a 250 amp. The amperage the alternator can output is directly related to the size of the windings, rectifier, and the amperage rating of the rectifier diodes. Installation: Before you get started always disconnect your battery. Voltage Regulator The fuse is housed in the little housing (fusible link block) mounted to the positive battery terminal. I called them as I was confused that they'd use a 200A fuse for either a 130A or 200A alternator.

Placing a diode in place of the Alt-S (alternator sensing) circuit fuse tricks the alternator into seeing less voltage than the battery actually has, raising the alternator voltage output. If this fuse blows, it can cause a range of issues that can be frustrating to diagnose and repair. The original wire just isn't large enough for proper power transfer. Should a power surge or spike occur, a fuse is replaced easily Most Electronic Voltage Regulators have 2 fuses, the ‘Charge’ or ‘Lamp’ fuse provides the sense voltage directly to the regulator while the ‘Engine’ fuse provides battery power to the Field Coil during and just after start-up when almost all of the alternator’s output is replentishing the battery.
