Driving w/o Instrument Cluster - Alternator Charging

[digger]

Has anyone figured out the best way to drive w/o a cluster and keep the alternator charging?

have read about guys putting a diode or bulb on the alternator circuit at the cluster connection. that's the circuit that gets broken shutting the alt down when the cluster is out.

edit: have not seen a pic of how it was done.

Doesn't the cluster have a resistor in the circuit?

"Note: Resistor allows alternator to charge if bulb burns out"

pretty sure it's dependent on model year.

Early 84-85 models did not have the bypass resistor. If the bulb goes out, the car doesn't charge.

well mine is not charging w/o the cluster. if the resistor is in the cluster then it wouldn't help if the cluster is removed but would if the bulb blew

The resistor connects the contact 14 (+12V) and 16 (charging system) of the C1 connector.

You can measure its resistance.

Is it in the harness or in the cluster itself? i dont have the cluster it is being refurbished.

do you have an etm? c1 is a 26pin blue connector at the back of the harness. should get unplugged to remove the cluster from the harness.
