Where is the location of the power module in a 85 ram 50?

The blower motor relay in the auxiliary junction box under the hood is good ? All relays ? only one controls the blower motor ! The electronic automatic temperature control module turns it on by supplying a ground inside the module ! The 30 amp fuse for the blower motor is located in the under hood auxiliary junction box ! At the relay socket test for battery voltage at pins 30 an 86 ,power form 30amp fuse ! The other two pins 85 an 87 ,85 is circuit to the electronic temperature control module . You could test this part of the circuit too , with a test light or volt meter . But if no voltage to the blower motor ,could be the electronic temperature control module is bad !

I looked at 86 power ram 50 starter in partsbook. The solenoid is on top of starter.

Dodge ram 85 spark plug gap is 35

I Would Say : Crank Sensor is Bad !

first thing clean battery connectors an post with baking soda an water solution an a piece of sand paper to get any rust off,keeping cables disconnected,next go under truck to where the starter is,an disconect the battery cable wire from starter an clean with sandpaper to get any debris off,check wires for cracks in the plastic covering,an check all wires leading from starter to battery an selenoid,another solution take hammer an hit starter a few times not to hard then try starting truck if that works it means you have a dead spot in your starter an need to replace it which is not hard.

it is on the firewall in most models, here is picture

I quote from the service manual:

"The Totally Integrated Power Module (TIPM) is a combination unit that performs the functions of the Power Distribution Center (PDC) and the Front Control Module. The TIPM is a printed circuit board based module that contains fuses, internal relays and a microprocessor that performs the functions previously executed by the FCM. The TIPM is located in the engine compartment, next to the battery and connects directly to the B+ cable via a stud located on top of the unit. The ground connection is via electrical connectors."


This link also provides interesting info on reflashing (re-programming) Dodge Ram TIPM module.

If you drive it very little what I would recommend is to install an electric fuel pump. That way after its been sitting all you have to do is turn the key on and the pump will fill the carb.

it is a pick up module in the distributer then to the coil!
