Overheating after electrical failure

[jackfrost]

I have a 90 LX with overheating issues. Recently I had a severe electrical failure
in the car. After replacing the solenoid,alternator,battery and fuse she was
running fine for 2 days. Today I just noticed that she was staying at 220 highway
or idle. I have a radiator and a blackmagic fan which are both just 2 years old,
Just replaced the thermostat (180) in Nov 07. I have also replaced the rad cap
some months ago. The only thing I haven't messed with is the water pump and
I'm not leaking any coolant. I've heard that a wrong ignition timing can contribute
to overheating, but I am not familliar in identifying if it is the problem. I'm all out of ideas, any help would be really really appreciated bros.

Check the engine to chassis ground, especially after having electrical problems.

The secondary power ground is between the back of the
intake manifold and the driver's side firewall. It is often missing or
loose. It supplies ground for the alternator, A/C compressor
clutch and other electrical accessories such as the gauges.
Any car that has a 3G or high output current alternator needs
a 4 gauge ground wire running from the block to the chassis
ground where the battery pigtail ground connects. [/B]
The 3G has a 130 amp capacity, so you wire the power side
with 4 gauge wire. It stands to reason that the ground side
handles just a much current, so it needs to be 4 gauge too.

Jeez....I'm an idiot I just checked all the fuses and found out my fan fuse was faulty. It actually burnt today. Repalced it and now works like a charm no more overheating issues. I'm going to do an overhaull on the wires make it neater to say. Thanks for the reply man.
