Starter Replacement

[91BroncoBoy]

I currently own a 91 4x4 EB with a 351. I use it to pull a 24ft travel trailer. Issue is, starter gets hot and won't restart when i refuel. I have to wait almost half an hour to restart. Any suggestions?

yo 91.,

Some possibilities;

"...Why are the cables and battery so important? The starter circuit pulls a lot of amperage, up to 500 amps depending on the starter, the engine load, and battery condition. This kind of amperage stresses all of the components in the starter circuit, including the battery, battery terminals, the battery disconnect switch, the cables including the ground path, and any remote solenoids. Problems with these components are hard to find because they appear fine at rest or under a light load, but generate high resistance under heavy amperage draws. The result will be low voltage to the starter during cranking, resulting in heavier amperage draw and increased internal heat in the starter. Over time, this will cause starter failure. Voltage measured at the starter during cranking should always be above 9.5VDC..."

Some add a ground cable to starter bolt to frame.

I've done a little more reading also and from what i have gathered, i should replace my starter with one that has a little more "torque"? i have already replaced battery, battery cables and terminals. everything works just fine until she runs for about an hour and i have to start her back up again, she gets real sluggish trying to start when shes warm!!!

yo,

 You can pull t and have it tested at an Automotive Electric Repair Shop.

I believe local parts stores just power it up with no other tests such as  Load Tests, etc;

Load Test

You can install the 92-96 Bronco  lighter, high torque Permanent Magnet Gear Reduction (PGMR) Starter

Call a mfgr such as PA Performance for install info;

 I don't know the year or model used

Ditto all what M5 said.....and add a heat shield between the exhaust and the starter.
