Techstream install
Install help?
I have installed & reinstalled the software. It seems to get hung up on the TISKEY. Any solutions?
Thanks.

So two 2 ohm filaments across 12 volts draw 72 watts. In series, two identical bulbs see 6 volts each. So to generate 18 watts each or 72 watts total, each filament would have its resistance down to 0.5 ohms.

Neglecting the change in resistance as temperature changes, here is a simpler way of looking at things.
The bulbs 65w rating will be at 13.8V, so filament resistance is (13.8 *13.8 /65) (R=V*V/P) or 2.93 ohms.
When the bulbs are in series the voltage across each bulb is 6.9V. The power dissipated across each bulb is (6.9*6.9/2.93) (P=V*V/R) or 16 watts.
So putting the bulbs in series changes the power from 65 Watts to 16 Watts (for a single bulb), which is 25% of normal. If we account for both bulbs the power drops from 130 Watts to 32 Watts, which is also 25%.
If we assume the cooler filament had 25% of the resistance (.7325 ohms), then the power across each bulb is (6.9*6.9/.7325) or 65 watts. This means it would be running at normal brightness again, which we know from observation is not true. So the true wattage of the bulbs in series is somewhere between 25% and 100%. We would need to measure the current to get an accurate measurement.

Really? My daughter's '97 Chevy Cavalier had DRL's exactly like that .

If the lamps were to have the same resistance in each state, the power to the lamps would be 12.5% compared to powering the lamps in parallel. Since the bulb resistance is lower when the filaments are cooler, the power consumption will be more than 12.5%. Maybe it could be 50% if the cooler DRLmode filaments have 25% as much resistance as the fullbrightess filament.
So two 2 ohm filaments across 12 volts draw 72 watts. In series, two identical bulbs see 6 volts each. So to generate 18 watts each or 72 watts total, each filament would have its resistance down to 0.5 ohms.

So the DRLs consume about 40% (52/130) of full power, not the 50% I previously thought. I do not have a curve for the exact bulb so there are some assumptions being made.
If they were 2 purely resistive loads, 65W/12.8V=5.08A, 12.8V/5.08A=2.52 ohms in each branch. In series the total resistance is 2.52*2=5.04 ohms 12.8V/5.04ohms=2.54A, 12.8V*2.54A=32.5W or 25% of full power total.

On the new version 7.31.00 software I install the software, installed the new driver and then copied the main menu file into the software following the directions in the activation file. I did not have to enter the key.
